Quizplus · Accepted Answer

In the cross BBGg × Bbgg, the possible gametes for the parent BBGg are BG and Bg, and for the parent Bbgg are bG and bg. Therefore, the possible outcomes in the F₂ generation are BbGG, BbGg, BBgg, and Bbgg. BbGG is not a possible outcome because it would require the parent BBGg to have produced a gamete carrying the recessive b allele, which is not possible.
