From a genetic standpoint, however, there is growing evidence that boys aren\’t more susceptible to autism, but rather girls are more protected from it. Yale researchers added to this thinking with new findings presented last week in which they looked at the DNA of several thousand children with autism.
They found that girls actually had substantially more high-risk genetic mutations associated with autism than boys, on average twice as many. Yet, because girls develop autistic features less often, something about being female is protective against the condition, said Stephan Sanders, a postdoctoral fellow at Yale University who presented the work.
Err, being X,X perhaps?
Given that X,o is (kinda) viable while Y,o most definitely ain\’t could this be part of the reason d\’ye think? Two X?
