Sex chromosome turnover is a procedure defined as when the sort of the sexual intercourse chromosome adjustments as a products of a modify in the id of the intercourse-figuring out genes (these types of as by mutation) or by a modify in their locale. There is 1 experimentally documented circumstance of sexual intercourse chromosome turnover happening for the duration of a 30-yr evolutionary experiment involving teleost fish (especially the swordtails), in which hybridization experiments resulted in a translocation of the sexual intercourse-determiner region of a sex chromosome into an autosome.
