Historical isolation facilitates species radiation by sexual selection: Insights from Chorthippus grasshoppers.

abstract：:Abstract Microsatellites are powerful molecular markers, used commonly to estimate intraspecific genetic distances. With the exception of band sharing similarity index, available distance measures were developed specifically for diploid organisms and are unsuited for comparisons of polyploids. Here, we present a simpl...
