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.

Answer:

Option A is  the correct answer.

D. 0 percent

Explanation:

As the widow's peak is dominant over straight hairline (w). And the mother is homozygous recessive dominant for widow's peak. So, her all children receive one dominant W from their mom so they all will be having widow's peak.
