Question

7. A widow's peak hairline is one that comes down to a point on the forehead. The allele that produces a widow's peak is dominant to the allele that produces a straight hairline. If two people that are heterozygous for the trait have children, determine the expected genotypic and phenotypic ratios of the offspring. Make sure to clearly identify the possible gametes the parents can make.
