Major difference between sex determination in drosophila and humans in Norman

The occurrence of female advantage, its proximal causes and its variation within and among gynodioecious species. X-chromosome inactivation: an essential feature of normal spermiogenesis in male heterogametic organisms. A number of these X genes have Y homologues, which may or may not carry out the same function as the X copy also see next section.

View Article Google Scholar 7. Even though the outcome of sex determination—whether an individual produces relatively few large ova or many small sperm—is strongly conserved, a bewildering number of underlying mechanisms can trigger development as either a male or female [3][4]. X-linked diseases present a range of phenotypes, from relatively benign colour blindness [47]through life-limiting Duchenne and Becker muscular dystrophies [48]to embryonic lethality, as in incontinentia pigmenti [49].
