The Nei's gene diversity per locus (HS) and Wright's inbreeding coefficient (FIS) were averaged over the native and invasive populations. The Wright's fixation index (FST) and an analogue unconstrained by gene diversity (F′ST) were averaged over the native and invasive populations or the whole dataset.
