Abstract
Gynandromorphism is relatively rare in anostracans and is generally thought to arise from mitotic aberrations occurring during early embryogenesis that create somatic-cell mosaics. We have reared 35 gynandromorphic Branchinecta, most of them being B. lindahli. The morphology of these individuals, the relatively high frequency of their occurrence, and their aggregation within sibships but not within pedigrees, indicate that they are not the result of mutational events. Their differential appearance in female-biased sibships suggests, instead, that the majority of them represent males that have been incompletely transformed into females by epigenetic feminizing factors.
