How can a parthenogenesis baby snake be male? I thought that sex in snakes is determined by sex chromosomes as in mammals. A female should them be able to supply only "female" chromosomes (X for lack of a better name, don't know if that;s how they are called in snakes). Shouldn't then parthenogenesis babies have only X chromosomes? How can a Boa produce males by parthenogenesis?
