No, it does not. And the math difference only appears at older ages, IIRC, and is quite small. I'm not sure exactly how this applies at the GT end of the spectrum, however.
Ah, just found something I have bookmarked about this (it's relevant to my job):
http://news.sciencemag.org/sciencenow/2008/07/24-01.html?ref=hp"Her team sifted through scores from standardized tests taken in 2005, 2006, and 2007 by nearly 7 million students in 10 states. Overall, the researchers found "no gender difference" in scores among children in grades two through 11. Among students with the highest test scores, the team did find that white boys outnumbered white girls by about two to one. Among Asians, however, that result was nearly reversed. Hyde says that suggests that cultural and social factors, not gender alone, influence how well students perform on tests."
