The little, stumpy Y chromosome—possessed by male mammals yet not females, and sometimes shrugged down as doing a bit more than determining the sex of a developing fetus—may effect individual biology in a huge method. Two studies that are independent figured the intercourse chromosome, which shrank scores of years back, keeps the couple of genes so it cannot by possibility, but as they are key to the survival. The findings may explain differences in also infection susceptibility between both women and men.
“The old textbook description claims that when maleness depends upon a few Y chromosome genes along with gonads, all the intercourse distinctions stem after that,” says geneticist Andrew Clark of Cornell University, who had been maybe maybe not associated with either research. Read more
