The little, stumpy Y chromosome—possessed by male mammals yet not females, and sometimes shrugged down as doing a bit more than determining the intercourse of a developing fetus—may effect individual biology in a huge means. Two studies that are independent figured the intercourse chromosome, which shrank scores of years back, keeps the number of genes it cannot by opportunity, but since they are key to the success. The findings may explain differences in also condition susceptibility between gents and ladies.
“The old textbook description claims that as soon as maleness depends upon a few Y chromosome genes along with gonads, all the sex differences stem after that,” says geneticist Andrew Clark of Cornell University, who had been maybe perhaps not tangled up in either research.
