Evolution of sex-dependent mtDNA transmission in freshwater mussels (Bivalvia: Unionida)

Abstract Doubly uniparental inheritance (DUI) describes a mode of mtDNA transmission widespread in gonochoric freshwater mussels (Bivalvia: Palaeoheterodonta: Unionida). In this system, both female- and male-transmitted mtDNAs, named F and M respectively, coexist in the same species. In unionids, DU...
