| 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.

It is known that parents are homozygous for dominant and recessive traits. Let’s make a diagram.
P AA x aa,
G A a,
