Question

The allele for a widow’s peak has complete dominance over the allele for a straight hairline (w). What is the probability of a man with a straight hairline (ww) and a woman with a widow’s peak (WW) having an offspring without a widow’s peak?

Answer 1

You need to do a Punnett square to figure out what genotypes the offspring will have. Then you need to interpret those genotypes in terms of phenotypes - what sort of appearances will the offspring of each genotype have? Is that sufficient guidance, or would you like me to work through the prob with you?

Answer 2

that is good, thank you.

Answer 3

Cool. :) You're quite welcome.
