The absence of small molars in humans is inherited as a dominant autosomal trait. Identify the possible genotypes

The absence of small molars in humans is inherited as a dominant autosomal trait. Identify the possible genotypes and phenotypes of parents and offspring if one of the spouses has small molars, while the other has none and is heterozygous for this characteristic. What is the likelihood of having children with this anomaly?

Genotypes and phenotypes P: aa – with small molars, Aa – without small molars;
genotypes and phenotypes of offspring: Aa – without small molars, aa – with small molars;
the probability of having children without small molars is 50%.
