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

Ithink its because more have died recently than in the past.
