Scientists discover genetic switch for egg and sperm – Livemint:

“Tokyo: In a first, Japanese researchers have found a genetic switch in vertebrates that determines whether germ cells become sperm or eggs. The gene is named foxl3, and has been identified in a small fish called Medaka (Oryzias latipes). Dr Toshiya Nishimura, Associate Professor Minoru Tanaka from the National Institute for Basic Biology, National Institutes of Natural Sciences in Japan and colleagues found that the foxl3 gene works in the germ cells of females ‘to suppress differentiation into sperm.’”
