Research Abstract |
In this study, we identified the sex-determining locus of Oryzias dancena by positional cloning, and found that this region on the Y chromosome contains an enhancer that upregulates the Sox3 specifically in gonads. Sex reversed phenotypes in transgenic fish and zinc-finger nuclease-induced mutants of the Y chromosomal Sox3 allele all point its critical role in sex determination, suggesting that the neo-Y chromosome of O. dancena arose by co-option of Sox3
