Question

Use the information gathered in the X-Linked Inheritance animation to answer the question. Since the white‑eye trait is X‑linked recessive, what result would you expect when crossing a heterozygous red‑eyed female with a white‑eyed male?

A. all red‑eyed females and all white‑eyed males

B. all red‑eyed males with half of the females having white and half of the females having red eyes

C. all red‑eyed progeny

D. all red‑eyed females with half of the males having white and half of the males having red eyes

E. In each sex, half of the offspring will have red and half of the offspring will have white eyes.

Note: The answer is not C.

Answer 1

Answer:

E. In each sex, half of the offspring will have red and half of the offspring will have white eyes.

Explanation:

The gene for eye color is sex-linked on X-chromosome.

W+ shows dominant allele for red eyes.

W shows recessive allele for white eyes.

For red eye in females, they can be homozygous or heterozygous and in males one allele for eye color is present on their X-chromosomes.
