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

Hey there!

Have you learned about punnet squares?

Can you set one up?

Remember: W is dominant so that means if you have Ww or WW, you're going to have the widow's peak
