Sex chromosome turnover is a procedure described as when the type of the sexual intercourse chromosome variations as a product of a improve in the identification of the sexual intercourse-figuring out genes (these kinds of as by mutation) or by a transform in their place. There is one experimentally documented case of intercourse chromosome turnover developing during a 30-year evolutionary experiment involving teleost fish (particularly the swordtails), in which hybridization experiments resulted in a translocation of the sexual intercourse-determiner area of a intercourse chromosome into an autosome. In a large amount of organisms, the intercourse-willpower devices presently observed are items of sex chromosome turnover. 46,XX testicular problem of intercourse development, also referred to as XX male syndrome, is a ailment in which folks with two X chromosomes in each individual cell, the pattern typically identified in women, have a male physical appearance. |
