Abstract

Analyses of mitochondrial DNA (mtDNA) have challenged the concept that genetic diversity within populations is governed by effective population size and mutation rate. A recent study in BMC Evolutionary Biology shows that variation in the rate of mutation rather than in population size is the main explanation for variations in mtDNA diversity observed among bird species.

基因多样性真的在大群体中更高吗?
线粒体DNA (mtDNA)的分析挑战了种群内遗传多样性由有效种群大小和突变率控制的概念。《BMC进化生物学》杂志最近的一项研究表明,鸟类mtDNA多样性的主要解释是突变率的变化,而不是种群大小的变化。
