Dimorphic sperm formation by sex-lethal
WebJul 7, 2011 · Primordial germ cells (PGCs) are able to differentiate into eggs or sperm. It is thought that PGCs do not assume a sexual fate until they reach the gonads, where sexual dimorphism is imposed by both the sex of the surrounding soma and cell-autonomous cues (1–3).In Drosophila, pole cells or PGCs differentiate to a male fate in response to … WebJun 1, 2024 · Sex-lethal (Sxl) encodes an RNA-binding protein that acts as the switch of sex determination in Drosophila and influences the genitalia formation and gonadal development.
