The tiny, stumpy Y chromosome—possessed by male mammals yet not females, and sometimes shrugged down as doing a bit more than determining the intercourse of the developing fetus—may effect individual biology in a large method. Two studies that are independent determined that the intercourse chromosome, which shrank scores of years back, keeps the a small number of genes it cannot by possibility, but since they’re key to your survival. The findings may explain differences in also illness susceptibility between both women and men.
“The old textbook description claims that when maleness is dependent upon a few Y chromosome genes along with gonads, all the intercourse distinctions stem after that,” says geneticist Andrew Clark of Cornell University, who was simply maybe perhaps perhaps not taking part in either research. […]
