Vedclass · Answer

(B) Mitochondrial inheritance is a form of cytoplasmic inheritance,which follows a maternal pattern because the egg cell contributes the vast majority of the cytoplasm and organelles to the zygote.During fertilization,the sperm cell typically contributes only its nucleus,while the mitochondria present in the sperm are usually degraded or excluded from the developing embryo.Since the parent with the mitochondrial mutation is used as the male parent,the mutation is not transmitted to the offspring.Therefore,the mutation will not be found in any of the $F_{2}$-progenies.

One of the parents of a cross has a mutation in its mitochondria. In that cross,that parent is taken as a male. During segregation of $F_{2}$-progenies,that mutation is found in:
