In humans, dominant alleles control whether you can roll your tongue and whether you have a widow's peak. People homozygous for the recessive alleles cannot roll their tongues and do not have a widow's peak. Suppose a tongue-rolling woman with a widow's peak marries a man who cannot roll his tongue and does not have a widow's peak. The first child of this couple cannot roll his tongue and does not have a widow's peak. What are the genotypes of the father, mother, and child?
