In humans, straight hair is a recessive gene, and wavy hair is a dominant one. What offspring can be expected

In humans, straight hair is a recessive gene, and wavy hair is a dominant one. What offspring can be expected from homozygous for dominant and recessiveness. Describe all genotypes and phenotypes.

Wavy hair is the dominant feature. We denote A.

Straight hair is a recessive trait. Let us denote a.

It is known that parents are homozygous for dominant and recessive traits. Let’s make a diagram.

P AA x aa,

G A a,

F1 Aa.

The offspring by the genotype is heterozygous Aa, by the phenotype – with wavy hair.
