White rabbit (aa) crosses with black rabbit (AA). Hybrid rabbits interbreed with each other.

White rabbit (aa) crosses with black rabbit (AA). Hybrid rabbits interbreed with each other. What offspring will they get?

It is clear that white is recessive. Hence, black is dominant. Both individuals are homozygous.

R. ♀ (denote a woman by recessive genes) aa x ♂ AA

G. a x A

F1 Aa.

This means that a 100% black rabbit will appear. Above the task is written in the correct format. P – parents. G – gametes. I wrote out one letter at a time because both parents are homozygous. If individuals are heterozygous (Aa), write out two letters. F – generation. Index 1 means the first generation.
