Quiz about Unit 6: The Human Genome

Question 1

In humans, the allele for having a cleft chin (C) is dominant over the allele for a smooth chin (c). One sister is homozygous dominant and the other sister is heterozygous. Which statement is true about the sisters?

Accepted Answer

Both will have a cleft chin

Answer

Both will have a smooth chin

Answer

One will have a cleft chin and the other will have a smooth chin.

Answer

Both will have a smooth chin and a cleft chin

Question 2

In rabbits, fur color is controlled by two alleles. The allele for brown fur is (B), and the allele for white fur is (b). A rabbit with the genotype Bb is crossed with a rabbit that is homozygous recessive (bb).
What percentage of the offspring is expected to have brown fur?

What percentage of the offspring is expected to have brown fur?

Accepted Answer

50%

Answer

25%

Answer

75%

Answer

100%

Question 3

In the Image: Which of the following statements best describes the inheritance of coat color in this species?

Accepted Answer

Coat color is sex-linked because it is located on the X chromosome.

Answer

All females will have black coats because they inherit two X chromosomes

Answer

Males cannot have a black coat because they inherit only one X chromosome.

Answer

The gene for coat color is located on the Y chromosome and affects only males.

Question 4

Hemophilia is a sex-linked recessive trait in humans caused by a gene located on the X chromosome. The allele for hemophilia is denoted as X^h, while the normal allele is X^H.

If a daughter is born with hemophilia, what is the probable genotypes of the parents?

Accepted Answer

Question 5

In humans, blood type is determined by the A, B, and O alleles. The A and B alleles are codominant, while the O allele is recessive. An individual with the AB genotype and an individual with the OO genotype can produce offspring with which of the following phenotypes?

Accepted Answer

A or B only

Answer

A, B, AB, or O

Answer

AB only

Answer

O only

Question 6

Based on the inheritance pattern, what are the possible genotypes for individual 2?

Accepted Answer

Dd only

Answer

DD only

Answer

Dd and DD

Answer
