Heteroplasmy in mitochondrial genetics refers to a cell containing

  • A.a mixture of normal and mutant mitochondrial DNA
  • B.two copies of every one of its nuclear chromosomes
  • C.mitochondria inherited from both parents equally
  • D.no mitochondrial DNA of any kind whatsoever

Answer: A

Because a cell holds many mitochondria, a mutation may be present in only some of them. The proportion determines whether symptoms appear, which is why mitochondrial disease varies so much in severity. Two tissues in one person can differ in their mutation load.
