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?
0 percent
75 percent
25 percent
50 percent

The answer in here is the first one: 0 percent. We know this 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.Hope this works for you my dear.
