1. In human beings, a downward-pointed frontal hairline ("widow's peak") is a heritable trait. A
person with a widow's peak always has at least one parent who also has this trait, whereas
people with a straight frontal hairline may occur in families in which one or even both parents
have widow's peaks. When both parents have a straight frontal hairline, all children also have
a straight hairline. Using A and a to symbolize alleles for this trait, what is the genotype of an
individual without a widow's peak? (Show your work)
