If a man who is heterozygous for PTC tasting marries a woman who is homozygous recessive, predict the potential genotypes and phenotypes for the offspring for that trait

Dominant allele - A

recessive allele - a

Hetero zygotic for PTC: Aa (expresses the allele)

Homo zygotic woman: aa (doesn't express it)

The cross: Aa x aa

The offspring's probability:

2/4 = 50% aa (homozygous recessive) - phenotype: feels the bitter taste

2/4 = 50% Aa (heterozygous) phenotype: doesn't feel the bitter taste of the PTC
