Question

Axial flowers are a dominant trait in pea plants, and terminal flowers are a recessive trait. Which genotype represents a plant that has homozygous dominant genes for axial flowers?

Answer 1

Let axial flowers have the dominant gene A.
Then terminal flowers will have the recessive gene a.
Homozygous means that the pair of genes is the same.
Since the axial flower is homozygous, its genes are homozygous dominant, so its genotype would be AA.

Answer 2

Let axial flowers have the dominant gene A.

Then terminal flowers will have the recessive gene a.

Homozygous means that the pair of genes is the same.

Since the axial flower is homozygous, its genes are homozygous dominant, so its genotype would be AA.
