[QUOTE="1982vett, post: 525619, member: 7795"] It's been 38 years since I sat in a biology class, but back then they taught us that the male and female chromosomes have to split. So XX becomes X and X, XY Becomes X and Y. Therefore their are as many X sperm as their are Y sperm. Natural service can't produce 85% Y and 15% X. However, I was taught in a government school where twisting of facts is the norm nowdays, but back then our school system still taught instead of pacified. [/QUOTE]
