Vedclass · Answer

(B) Hybrid breakdown is a type of reproductive isolation where the hybrid offspring are viable and fertile,but their subsequent generations ($F_2$ and beyond) are feeble,sterile,or physiologically inferior.This phenomenon occurs because the genetic combinations in the $F_2$ generation may lead to deleterious interactions between genes that were previously masked in the $F_1$ generation.

Hybrid breakdown refers to the condition where the $F_2$ generation or subsequent generations of a hybrid cross are physiologically inferior or less viable compared to the $F_1$ generation.
