The gene for early ripeness of oats dominates over the gene that determines late ripeness

The gene for early ripeness of oats dominates over the gene that determines late ripeness. They crossed heterozygous early ripe with post ripe ones. Find F1.

Let’s designate the gene that determines the early ripeness as A, then the gene responsible for the late ripening of oats will be a.

Heterozygous early maturing plants will be Aa, their germ cells will be A and a.

Late-ripening oats – aa, the same type of gametes of which will be written as a.

Variants of offspring from crossing the designated plants:

early ripe plants (Aa) – 50%

late-ripening plants (aa) – 50%.
