- 1.
What are pedigrees?
- A.
A chart that shows the presence or absence of a trait according to relationships within a family across several generations.
- B.
What you need to enter a dog or cat show.
- C.
A brand of puppy kibble.
- D.
IDK
Correct Answer
A. A chart that shows the presence or absence of a trait according to relationships within a family across several generations.Explanation
Pedigrees are charts that display the inheritance of traits within a family over multiple generations. They show the presence or absence of a specific trait and help trace its pattern of inheritance. By examining the relationships between family members, pedigrees provide valuable information about genetic disorders, hereditary diseases, and the likelihood of passing on certain traits to future generations.Rate this question:

What do pedigrees show?
- A.
The presence or absence of a trait in a family tree.
- B.
Blood-line
- C.
A biological family tree
- D.
IDK
Correct Answer
A. The presence or absence of a trait in a family tree.Explanation
Pedigrees are graphical representations of a family tree that depict the presence or absence of a specific trait or condition within a lineage. They are commonly used in genetics to study the inheritance patterns of traits and to track the occurrence of genetic disorders within families. By analyzing pedigrees, scientists can determine whether a trait is inherited in a dominant or recessive manner, identify carriers of genetic disorders, and predict the likelihood of certain traits being passed on to future generations.Rate this question:

Which of the following explain how to read a pedigree?
- A.
Circle = Male Square = Female
- B.
Solid shape = Trait present Empty shape = Trait absent
- C.
Circle = Female Square = Male
- D.
Solid shape = Trait absent Empty shape = Trait present
- E.
IDK
Correct Answer(s)
B. Solid shape = Trait present Empty shape = Trait absent
C. Circle = Female Square = MaleExplanation
The given answer correctly explains how to read a pedigree. In a pedigree, solid shapes represent the presence of a trait, while empty shapes represent the absence of a trait. Additionally, circles represent females and squares represent males. Therefore, the answer correctly states that solid shape represents trait present, empty shape represents trait absent, circle represents female, and square represents male.Rate this question:

What are Karyotypes?
- A.
Types of kareoke machines.
- B.
A micrograph of a complete diploid set of chromosomes grouped together in pairs that is arranged in order of decreasing size.
- C.
IDK
Correct Answer
B. A micrograph of a complete diploid set of chromosomes grouped together in pairs that is arranged in order of decreasing size.Explanation
Karyotypes are micrographs of complete diploid sets of chromosomes. They show the chromosomes grouped together in pairs and arranged in order of decreasing size. This allows scientists to study and analyze the structure, number, and behavior of chromosomes in an individual. Karyotypes are used in genetics to identify chromosomal abnormalities, such as Down syndrome or Turner syndrome. They provide valuable information about an individual's genetic makeup and can help diagnose genetic disorders.Rate this question:

What do Karyotypes show?
- A.
Music by Lady Gaga
- B.
Music by Elvis
- C.
Pairs of Chromosomes
- D.
IDK
Correct Answer
C. Pairs of ChromosomesExplanation
Karyotypes are visual representations of an individual's chromosomes, arranged in pairs. They provide information about the number, size, and shape of chromosomes, allowing scientists to identify any abnormalities or genetic disorders. By examining karyotypes, we can determine the sex of an individual and detect chromosomal disorders such as Down syndrome or Turner syndrome. Therefore, karyotypes show pairs of chromosomes.Rate this question:
