Aheterozygous pea plant that is tallwith yellow seed? ttyy is allowed to self-fertilize. what is the probability that an off spring will be eithertall with yellow seeds tall with green seeds, or dwarf with yellow seeds

Such a cross would result in (Ty ty) x (Ty ty) = TTyy, Ttyy, Ttyy, ttyy. Thus, tall with yellow seeds is 75%, dwarf with yellow seed is 25%. There is 0 chance for green seed since the yellow gene was homozygous crossed.
