Animals have evolved a bewildering diversity of mechanisms to determine the two sexes. Studies of sex determination genes β their history and function β in non-model insects and __Drosophila__ have allowed us to begin to understand the generation of sex determination diversity. One common theme from
The sex-determining gene SRY was screened for molecular alteration in an XY sex-reversed female by single-strand conformation polymorphism (SSCP) technique. An A-to-G transition was detected which leads to an exchange of a tyrosine by a cysteine in the SRY protein. The affected tyrosine residue loca
## Abstract Summary: The __herβ1__ regulatory switch gene in __C. elegans__ sex determination is normally active in __XO__ animals, resulting in male development, and inactive in __XX__ animals, allowing hermaphrodite development. The __herβ1(n695gf)__ mutation results in the incomplete transformat
