Question

A "widow's peak” hairline in humans is coded by the dominant
allele W. A straight hairline is coded by the recessive allele w. A
man with a homozygous dominant WWproduces a zygote with a
woman with a heterozygous dominant Ww for the trait. Which
allele combinations could occur in the zygote?

Answer 1

Answer:

WW and Ww

Explanation:

There is a 50% chance of the zygote being homozygous dominant and 50% chance of the zygote being a heterozygous dominant. The zygote will have a widow's peak hairline in both cases.
