The Process Of Meiosis! Biology Trivia Questions Quiz

1.

What process creates haploid sex cells (gametes)?

Explanation
Meiosis is the process that creates haploid sex cells, also known as gametes. During meiosis, a diploid cell undergoes two rounds of division, resulting in four haploid cells. These haploid cells, such as sperm and eggs, contain half the number of chromosomes as the original cell. This reduction in chromosome number is essential for sexual reproduction, as it ensures that when gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes. Therefore, meiosis is responsible for the production of gametes in organisms.

Where does meiosis take place in males?

Explanation
Meiosis is the process of cell division that produces gametes, such as sperm cells in males. In males, meiosis takes place in the testes. The testes are the primary reproductive organs responsible for producing sperm cells through the process of spermatogenesis. Within the testes, specialized cells called spermatogonia undergo meiosis to produce haploid sperm cells, which are then released for fertilization. Therefore, the correct answer is testes.

Where does meiosis take place in females?

Explanation
Meiosis takes place in the ovaries of females. During meiosis, the ovaries undergo a specialized form of cell division that results in the production of eggs or ova. This process is essential for sexual reproduction as it ensures the formation of haploid gametes with half the number of chromosomes. The ovaries contain numerous follicles, each containing an immature egg. These eggs undergo meiosis to form mature eggs that can be fertilized by sperm. Therefore, the correct answer is ovaries.

When chromosomes exchange traits this is called ___________________.

Explanation
Crossing over refers to the process in which chromosomes exchange genetic material during meiosis. This exchange of genetic material leads to the recombination of traits between homologous chromosomes, resulting in genetic diversity. It is an essential mechanism for genetic variation and plays a crucial role in evolution.

5.

Which pair of chromosomes determines sex of the offspring?

Explanation
The pair of chromosomes that determines the sex of the offspring is chromosome number 23. In humans, females have two X chromosomes (XX) while males have one X and one Y chromosome (XY). The presence of the Y chromosome in males determines their sex.

6.

How many new cells are produced at the end of telophase II?

Explanation
During telophase II, the two haploid cells formed during meiosis I divide further, resulting in the formation of four new cells. This is because the chromosomes have already been separated during anaphase II, and now the cytoplasm divides to create two new cells from each of the two cells. Therefore, at the end of telophase II, four new cells are produced.

7.

Pairs of chromosomes with the same traits are called ______________________ pairs.

A.

Homologous
B.

Chromatids
C.

Sister
D.

Option 4

Correct Answer
A. Homologous

Explanation
Homologous pairs of chromosomes are pairs that have the same genes in the same order, although they may have different versions of those genes. These pairs are found in diploid organisms, where each chromosome in the pair comes from one parent. Homologous pairs are important during meiosis, as they undergo crossing over, which leads to genetic variation. Therefore, homologous is the correct term to describe pairs of chromosomes with the same traits.

Sex cells, like sperm and eggs, have only half a set of chromosomes making them ____________ cells.

A.

Diploid
B.

Haploid
C.

Sex
D.

Option 4

Correct Answer
B. Haploid

Explanation
Sex cells, such as sperm and eggs, have only half a set of chromosomes, meaning they contain one set of chromosomes instead of the usual two sets found in most cells. This makes them haploid cells. Haploid cells are important for sexual reproduction as they combine during fertilization to form a new individual with a complete set of chromosomes.
