Picking the sex of a baby one step closer as scientists separate X and Y-chromosome-carrying sperm: 'the implications would be colossal'

of a potential use for their research."In dairy farms, the value of female cows is much higher than male cows, because milk is only produced by the female cow. In the case of beef meet production, the speed of growing is much higher in male after castration than female. Thus, the value of male calves is higher than female."

He asked why the researchers didn't replicate the work in other species, but added:"I doubt it will be long before someone has a look though!" :"This study gives us a wider understanding of how sperm are made. During meiosis—the kind of cell division that makes sperm, the X chromosome has been thought to be 'turned off', with special genes on other chromosomes replacing those on the X, and these other genes would be shared between X and Y bearing sperm. During the later stages of sperm manufacture, many genes are turned off anyway, as the sperm head becomes.

"If X and Y bearing human sperm have similar differences, then in theory they could also be separated in a similar way. However, the receptors on sperm can be often different between species, so it is not a given that this would work, and there would be a lot of important ethical and safety questions before any application to humans."Newsweek
