Quiz On 10 Meiosis And Sexual Reproduction
During sexual reproduction there is a lot that takes place to see the youngling produced after the gestation period. The cells are broken up and come together to form the offspring. Take the review quiz below on chapter 10 on meiosis and sexual reproduction to see how well you understand the process.
Questions and Answers
- 1.
__________ reproduction is easier and faster than __________ reproduction. It takes less energy. But, sexual reproduction allows for greater genetic diversity.
- A.
Sexual, asexual
- B.
Asexual, sexual
Correct Answer
B. Asexual, sexualExplanation
Asexual reproduction is easier and faster than sexual reproduction because it does not require the involvement of two individuals or the production of gametes. Asexual reproduction allows an organism to produce offspring without the need for a mate, which saves time and energy. However, sexual reproduction allows for greater genetic diversity because it involves the combination of genetic material from two parents, resulting in offspring with unique genetic traits.Rate this question:

Chromosomes are duplicated in ______ cells. Clue: 4 letter word
Correct Answer
germExplanation
Chromosomes are duplicated in germ cells. Germ cells are the reproductive cells that give rise to eggs or sperm. During the process of meiosis, germ cells undergo chromosome duplication, followed by two rounds of cell division, resulting in the formation of haploid gametes with half the number of chromosomes as the parent cell. This allows for the combination of genetic material from two parents during fertilization, maintaining the correct chromosome number in the offspring.Rate this question:
- 3.
Asexual reproduction- a. single parent produces ___________. b. Offspring are exactly like the parent.
- A.
Clones
- B.
Variables
Correct Answer
A. ClonesExplanation
Asexual reproduction is a type of reproduction in which a single parent produces offspring that are exactly like the parent. These offspring are called clones because they have the same genetic information as the parent and are genetically identical to each other. This process does not involve the combination of genetic material from two parents, resulting in offspring that are variable or different from the parent. Therefore, the correct answer is "clones."Rate this question:

_________ are different (alternative) forms of a gene.
- A.
Alleles
- B.
Chromatids
- C.
Gametes
Correct Answer
A. AllelesExplanation
Alleles are different forms of a gene that can exist at the same locus on a chromosome. They can vary in their DNA sequence and can result in different traits or characteristics. Each individual inherits two alleles for each gene, one from each parent. These alleles can be dominant or recessive, determining the expression of the trait. Therefore, alleles are alternative versions of a gene that contribute to genetic diversity within a population.Rate this question:

Each pair of chromosomes in a diploid cells is called a ___________ pair.Clue: Word begins with the letter H
Correct Answer
homologousExplanation
In a diploid cell, each pair of chromosomes is called a homologous pair. Homologous chromosomes are similar in size, shape, and carry genes for the same traits. They are derived from each parent, with one chromosome coming from the mother and the other from the father. During meiosis, homologous chromosomes pair up and exchange genetic material through a process called crossing over, which contributes to genetic diversity. Homologous pairs play a crucial role in maintaining the stability and genetic integrity of an organism.Rate this question:
- 6.
_________ are sex cells which are haploid, and arise from germ cells which are diploid.
Correct Answer
GametesExplanation
Gametes are the sex cells that are haploid, meaning they contain half the number of chromosomes compared to other cells in the body. They are formed from germ cells, which are diploid, meaning they have a full set of chromosomes. Gametes are responsible for sexual reproduction, as they combine during fertilization to form a new individual with a complete set of chromosomes.Rate this question:

Meiosis cuts the chromosome number in __________.Clue: (46---> 23)
- A.
Half
- B.
Thirds
- C.
Fifths
Correct Answer
A. HalfExplanation
Meiosis is a type of cell division that occurs in sexually reproducing organisms. It involves two rounds of division, resulting in the formation of four daughter cells with half the number of chromosomes as the parent cell. In humans, the parent cell has 46 chromosomes, and through meiosis, the chromosome number is reduced to 23 in each daughter cell. Therefore, the correct answer is "half" because meiosis cuts the chromosome number in half.Rate this question:
-

Meiosis cuts the chromosome number in half. Therefore , the daughter cells from meiosis are ____________.
- A.
Diploid
- B.
Haploid
Correct Answer
B. HaploidExplanation
During meiosis, the chromosome number is reduced by half. This is because the process involves two rounds of cell division, resulting in four daughter cells with half the number of chromosomes as the parent cell. These daughter cells are called haploid cells. Haploid cells contain a single set of chromosomes, whereas diploid cells have two sets. Therefore, the correct answer is haploid.Rate this question:

Meiosis occurs in 2 phases; each phase undergoes nuclear division. So there are a total of ____ daughter cells from meiosis.
Correct Answer
4
fourExplanation
Meiosis is a type of cell division that occurs in two phases, known as meiosis I and meiosis II. During meiosis I, the cell undergoes a reduction division, resulting in two daughter cells. These daughter cells then enter meiosis II, where they undergo a second round of nuclear division. As a result, each of the two daughter cells from meiosis I divides again, resulting in a total of four daughter cells at the end of meiosis. Therefore, the correct answer is 4 or four.Rate this question:
- 10.
The 2 phases of meiosis are called meiosis I and __________.
Correct Answer
meiosis II
meiosis 2Explanation
The correct answer is "meiosis II" or "meiosis 2". Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce gametes. It consists of two consecutive divisions called meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, while meiosis II involves the separation of sister chromatids. Therefore, the correct answer is meiosis II or meiosis 2.Rate this question:
- 11.
Crossing over of the gametes occurs during prophase 1 of ______________.
- A.
Meiosis II
- B.
Meiosis I
Correct Answer
B. Meiosis IExplanation
During prophase 1 of meiosis I, crossing over of the gametes occurs. This is the stage where homologous chromosomes pair up and exchange genetic material through a process called recombination. This crossing over results in genetic variation as it shuffles the genetic information between the chromosomes. Meiosis II, on the other hand, is the stage where the sister chromatids separate, resulting in the formation of four haploid daughter cells. Therefore, the correct answer is meiosis I.Rate this question:
-
- 12.
In crossing over, gene segments "mix and match " between the non sister ___________ of each homologous pair. As a result, each daughter cell has some of the father's genes and some of the mother's gene.Clue: A smaller chromosome
Correct Answer
chromatids
chromatidExplanation
During crossing over, gene segments "mix and match" between the non-sister chromatids of each homologous pair. This process occurs during meiosis and leads to genetic recombination. As a result, each daughter cell ends up with a combination of genes from both parents. In this context, the term "chromatids" refers to the two identical copies of a chromosome that are held together by a centromere. Therefore, the correct answer is chromatids and chromatid.Rate this question:
- 13.
The primary _________ divides and produces a secondary oocyte and a polar body. The polar body will not develop into a gamete.
Correct Answer
oocyteExplanation
The primary oocyte is the initial cell in the process of oogenesis, which is the formation of female gametes (eggs). During this process, the primary oocyte undergoes meiosis, a type of cell division, which results in the production of a secondary oocyte and a polar body. The secondary oocyte is the mature egg that has the potential to be fertilized, while the polar body is a smaller non-functional cell that does not develop into a gamete. Therefore, the primary oocyte is responsible for dividing and producing these two distinct cells.Rate this question:

During Metaphase I, the chromosomes of each pair are randomly aligned along the _________.
- A.
Edges
- B.
Center
- C.
Top
- D.
Bottom
Correct Answer
B. CenterExplanation
During Metaphase I, the chromosomes of each pair are randomly aligned along the center. This is because during this phase of meiosis, homologous chromosomes pair up and line up along the equator of the cell. This alignment is important for the subsequent separation of the chromosomes during Anaphase I, where one chromosome from each pair will be pulled to opposite poles of the cell.Rate this question:
-
- 15.
The stages of meiosis I and II are called the _____ as in mitosis. The chromosomes move in the same way.
- A.
Same
- B.
Opposite
Correct Answer
A. SameExplanation
In meiosis I and II, the stages are called the same as in mitosis because the process of chromosome movement is similar. During both meiosis and mitosis, the chromosomes go through stages like prophase, metaphase, anaphase, and telophase. In these stages, the chromosomes align, separate, and move to opposite poles of the cell. Therefore, the term "same" accurately describes the similarity in the stages and chromosome movement between meiosis and mitosis.Rate this question:

___________ is the process of the male and female gametes uniting and the nuclei fusing.
- A.
Hypnosis
- B.
Photosynthesis
- C.
Fertilization
Correct Answer
C. FertilizationExplanation
Fertilization is the process of the male and female gametes uniting and the nuclei fusing. During fertilization, the sperm cell from the male and the egg cell from the female combine to form a zygote. This process is essential for sexual reproduction in organisms, as it leads to the formation of a new individual with a unique combination of genetic material from both parents.Rate this question:

The fusion of 2 haploid nuclei results in the diploid __________.
- A.
Zygote
- B.
Oocyte
- C.
Billy goat
Correct Answer
A. ZygoteExplanation
The fusion of 2 haploid nuclei results in the formation of a diploid zygote. The term "diploid" refers to having two sets of chromosomes, one from each parent. In sexual reproduction, the fusion of the haploid nuclei from the male and female gametes (sperm and egg) forms a zygote, which is the first cell of a new individual with a complete set of chromosomes. The zygote then undergoes further development and cell division to eventually form a fully developed organism.Rate this question:

What are the number of daughter cells in: Mitosis _____ - Meiosis _____.answer format: 1 and 2
Correct Answer
2 and 4
two and fourExplanation
In mitosis, one cell divides into two daughter cells. Therefore, the number of daughter cells in mitosis is 2. In meiosis, one cell undergoes two rounds of division, resulting in the formation of four daughter cells. Therefore, the number of daughter cells in meiosis is 4. Both the numerical format (2 and 4) and the word format (two and four) indicate the correct number of daughter cells in mitosis and meiosis.Rate this question:
- 19.
Choose one:Mitosis (haploid or diploid)
Correct Answer
diploidExplanation
Mitosis is a type of cell division that occurs in somatic cells, which are diploid. Diploid cells have two sets of chromosomes, one inherited from each parent, and undergo mitosis to produce identical daughter cells with the same number of chromosomes as the parent cell. This process ensures the maintenance of the diploid chromosome number in the body cells, allowing for growth, repair, and replacement of damaged or old cells. Therefore, the correct answer is diploid.Rate this question:
- 20.
Choose one:Meiosis (haploid or diploid)
Correct Answer
haploidExplanation
Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce gametes (sperm and egg cells). During meiosis, the cell undergoes two rounds of division, resulting in the formation of four daughter cells with half the number of chromosomes as the parent cell. These daughter cells are haploid, meaning they contain only one set of chromosomes. Therefore, the correct answer is haploid.Rate this question:
- 21.
Which process features the functions of Growth and repair and also Asexual reproduction?
- A.
Mitosis
- B.
Meiosis
Correct Answer
A. MitosisExplanation
Mitosis is the correct answer because it is a process that involves the growth and repair of cells. During mitosis, a single cell divides into two identical daughter cells, which is a form of asexual reproduction. This process is responsible for the growth and maintenance of tissues and organs in multicellular organisms, as well as the repair of damaged or injured tissues. Meiosis, on the other hand, is a process that involves the formation of gametes (sex cells) and is not directly involved in growth, repair, or asexual reproduction.Rate this question:
-
- 22.
Which process features the function of Sexual reproduction?
- A.
Mitosis
- B.
Meiosis
Correct Answer
B. MeiosisExplanation
Meiosis is the process that features the function of sexual reproduction. During meiosis, the number of chromosomes is halved, resulting in the formation of gametes (sperm and eggs) with half the number of chromosomes as the parent cells. This reduction in chromosome number is important for sexual reproduction because when the gametes fuse during fertilization, the resulting offspring will have a complete set of chromosomes. In contrast, mitosis is a process of cell division that produces genetically identical daughter cells and is involved in growth, repair, and asexual reproduction.Rate this question:

Mitosis offspring produces clones.Meiosis offspring produces _________. (Clue: letter begins with a V)
Correct Answer
variety
variables
varieties
variableExplanation
In mitosis, the offspring produced are genetically identical to the parent cell, resulting in clones. However, in meiosis, the offspring produced are genetically diverse due to the process of genetic recombination. This genetic recombination leads to the production of a variety of offspring with different combinations of genetic traits. Therefore, the correct answer is "variety, variables, varieties, variable" as all these options represent the diversity of offspring produced by meiosis.Rate this question:
- 24.
True or falseIn mitosis daughter cells are the same from parent.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In mitosis, the daughter cells are indeed identical to the parent cell. This is because during mitosis, the parent cell divides into two daughter cells, and each daughter cell receives an exact copy of the genetic material from the parent cell. Therefore, the daughter cells have the same genetic information and are essentially clones of the parent cell.Rate this question:
-
- 25.
Daughter cells are different from parent in?
- A.
Mitosis
- B.
Meiosis
Correct Answer
B. MeiosisExplanation
Daughter cells are different from the parent cells in meiosis because meiosis is a type of cell division that results in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This process involves two rounds of cell division, resulting in four genetically diverse daughter cells. In contrast, mitosis is a type of cell division that produces two identical daughter cells, each with the same number of chromosomes as the parent cell. Therefore, meiosis is responsible for genetic variation and the creation of unique offspring.Rate this question:

In Mitosis cells are derived from ________ cells.
- A.
Blood cells
- B.
Germ cells
- C.
Somatic Cells
Correct Answer
C. Somatic CellsExplanation
Mitosis is a process of cell division that occurs in somatic cells, which are all the cells in the body except for the reproductive cells (germ cells). Blood cells are a type of somatic cell, but not all somatic cells are blood cells. Therefore, the correct answer is somatic cells.Rate this question:
-
- 27.
In meiosis cells are derived from ______ cells.
- A.
Somatic cells
- B.
Germ cells
- C.
Stem cells
Correct Answer
B. Germ cellsExplanation
Meiosis is a type of cell division that occurs in germ cells, which are specialized cells that give rise to gametes (sperm and eggs). Somatic cells, on the other hand, are non-reproductive cells that make up the majority of the body's tissues and organs. Stem cells are undifferentiated cells that have the potential to develop into different types of cells, including both somatic and germ cells. However, in the context of meiosis, it is specifically the germ cells that undergo this type of cell division.Rate this question:
