[Extract].....The analysis also found that the obsessively debated differences between men and women were, at least on the genetic level, even greater than previously thought. As many as 300 of the genes on the X chromosomes may be activated differently in women than in men, says the other author of the paper, Laura Carrel, molecular biologist at the Pennsylvania State University College of Medicine.
The newly discovered genetic variation between women might help account for differing gender reactions to prescription drugs and the heightened vulnerability of women to some diseases, experts say.
"The important question becomes how men and women actually vary and how much variability there is in females," Carrel says. "We now might have new candidate genes that could explain differences between men and women."
All told, men and women may differ by as much as 2 per cent of their entire genetic inheritance, greater than the hereditary gap between humankind and its closest relative, the chimpanzee. "In essence," Willard says, "there is not one human genome, but two: male and female."
