Evidence for variation in the effective population size of animal mitochondrial DNA. [PDF]
PLoS ONE, 2009 It has recently been shown that levels of diversity in mitochondrial DNA are remarkably constant across animals of diverse census population sizes and ecologies, which has led to the suggestion that the effective population of mitochondrial DNA may be ...
