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?
I chose 75% due to the dominant gene rom the woman (WW). I did the punnett square and I end up getting three with the dominant trait, so I say it would be 75%Is this wrong?

i would agree, i recieved the same answer, when i worked the problem out, good job
oh wow, thank you very much.
Because 1 parent (the mom) has both WW alleles, all (100%) of the offspring will have the widow's peak.
Since the answer asks "what is the probability of having an offspring without a widow’s peak?" the answer is 0.
