Escape from an ancient, ancestral sex chromosome system  (Shinisaurus crocodilurus) and the first-time implication of Foxl2 as a primary sex determining gene in a vertebrate
We used a combination of previously published whole genome re-sequencing in conjunction with these RADseq data to show that S. crocodilurus has replaced the ancestral anguimorph ZW system on LG7 with a novel ZW system on LG3.
