"Although this pattern of inheritance leaves men vulnerable to a host of X-linked disorders, Hameister contends that it also positions them to reap the rewards of rare, beneficial X-linked mutations, which may explain why men cluster at the ends of the intelligence spectrum. "Females tend to do better overall on IQ tests; they average out at about 100, while men average about 99," Hameister says. "Also, more men are mentally retarded. But when you look at IQs at 135 and above, you see more men."

Quote from ha8mo's link.  That explains why more boys get 5**.
