摘要:Few amphibians possess morphologically distinguishable heteromorphic sex chromosomes.The classic indirect method is a time-consuming and resource-demanding task to identify the heterogametic sex.Here we have taken advantage of a sex-specific microsatellite marker,by amplifying a large number of samples of known male and female individuals from various populations,to reveal a homogeneous pattern of male heterogamety in Quasipaa boulengeri.The identification of the heterogametic sex will help interpreting the evolution of sex determination.Besides relevance for evolutionary studies of sex determination,the sex-linked markers have potential for addressing practical issues in conservation biology because the sex reversal that caused by anthropogenic endocrine disruptors is considered as a reason for amphibian decline.
