Quizplus · Accepted Answer

Mitochondrial genes are only inherited maternally, meaning they are passed on from a person's mother. This is because eggs, which are formed in a female's ovaries, contain mitochondria, while sperm, which are formed in a male's testes, do not contribute mitochondria to the offspring. Therefore, all mitochondrial genes are inherited from one's mother.
