Comparative genetics of sex determination: masculinizing mutations in Caenorhabditis briggsae.

The nematodes Caenorhabditis elegans and C. briggsae independently evolved self-fertile hermaphroditism from gonochoristic ancestors. C.

Sex determination across evolution: connecting the dots.

Sexual differentiation appears to be an ancient, and potentially homologous, feature of animal biology, and yet the pathways that underlie the process exhibit bewildering variety
