Question

If the white-eye trait were X-linked dominant rather than X-linked recessive, what result would you expect when crossing a heterozygous white-eyed female with a red-eyed male?

Answer 1

In an X-linked dominant inheritance pattern, the dominant allele on the X chromosome would be sufficient to express the white-eye trait. Therefore, all offspring from this cross would have the white-eye trait, regardless of the sex of the offspring.

Step-by-step explanation:

If the white-eye trait were X-linked dominant rather than X-linked recessive, the result when crossing a heterozygous white-eyed female with a red-eyed male would be different. In an X-linked dominant inheritance pattern, the dominant allele on the X chromosome would be sufficient to express the white-eye trait. Therefore, all offspring from this cross would have the white-eye trait, regardless of the sex of the offspring.
