7. A couple with widow's peaks, an autosomal dominant trait, have two grown daugh- ters and one grown son. The daughters do not have a widow's peak (straight hair line). Their son does have a widow's peak. He married a straight hair lined woman, and they have two daughters. Draw a pedigree that represents this scenario tracking the straight hair lined trait. Make sure to label all generations and provide genotypes for each individual on the pedigree. potential
