Based on the image, which inheritance pattern best explains the difference between a widow's peak and no widow's peak in humans?

If the allele for widow's peak (A) is dominant over the allele for no widow's peak (a), what is the expected genotype ratio of the offspring from a cross between a homozygous widow's peak parent (AA) and a heterozygous widow's peak parent (Aa)?

A person with genotype Aa for the widow's peak gene has children with someone who is aa. What percentage of their children are expected to have a widow's peak?
