Answer:
The correct answer is - man will have widow's peak.
Explanation:
A widow's peak is a distinctive, V-shaped hairline that tends to run in families and is a genetic trait. It is a dominant trait that can be represented by the W allele whereas the no hairline or no widow's peak is represented by the w allele.
If a man is heterozygous for this trait which means the Ww then he will possess the widow's peak as in his phenotype as the W allele masks the expression of the w allele.
