Mitochondrial DNA is inherited from :
Answer: C
Mitochondrial DNA is inherited from the mother.
Mitochondria are passed on through the egg's cytoplasm. The few paternal mitochondria in the sperm are destroyed after fertilisation, so a person's mtDNA is the same as their mother's, their siblings' and all their maternal relatives'. This makes it useful in forensic identification when nuclear DNA is degraded, as in old bones, teeth and hair shafts.
It is not inherited from the father or from both parents; that is nuclear DNA. Father-to-son inheritance is the pattern of the Y chromosome.
