  1. For each taxonomic group of freshwater mussels, the number of species and mtDNAs considered in this study are given, as well as the number and kind of ORFans (F-, M-, or H-orfs) retrieved from them. mtDNA types: F and M, female- and male-transmitted mtDNAs of dioecious DUI species, respectively; H, mtDNA of stably hermaphroditic species that lost DUI sensu [3]; non-DUI, mtDNA of dioecious and hermaphroditic non-DUI species. mtDNAs of dioecious species carrying an F-orf but for which no evidence of DUI has been produced yet, or of dioecious DUI species that can show occasional hermaphroditism, were considered as F for simplicity
