Vedclass · Answer

(B) Mitochondrial $DNA$ is inherited exclusively through the cytoplasm of the egg cell (maternal inheritance).Since the parent with the mitochondrial mutation is used as the male,the sperm contributes only nuclear $DNA$ and virtually no cytoplasm to the zygote.Therefore,the mitochondrial mutation is not transmitted to the $F_1$ generation,and consequently,it will not be present in the $F_2$ generation.Thus,the mutation is not observed in any offspring.

In a cross,one parent has a mutation in its mitochondria. In this case,this parent is taken as the male. During analysis,in which offspring is this mutation observed in the $F_2$ generation?
