For example, for the dioecious softshell clam Mya arenaria (Linnaeus, 1758) no triploids developed as males, and most triploids were females with a few being undifferentiated, which led to the proposal of a sex-determination mechanism similar to that found for Drosophila, in which triploids XXX and XXY are all-female regardless of the Y-chromosome. In dioecious dwarf surfclam Mulinia lateralis (Say, 1822), it has been also found that its gynogenetic progeny are all females indicating that they must be the homogametic sex (carrying 2X-chromosomes), and triploids showed both genders, males and females, such that it was proposed that they were XXX and XXY, with the Y-chromosome being dominant over the X-chromosome.
