Linkage disequilibrium and recombination in hominid mitochondrial DNA.
Awadalla P., Eyre-Walker A., Smith JM.
The assumption that human mitochondrial DNA is inherited from one parent only and therefore does not recombine is questionable. Linkage disequilibrium in human and chimpanzee mitochondrial DNA declines as a function of the distance between sites. This pattern can be attributed to one mechanism only: recombination.
