It could be that mathematical ability is genetic and normally distributed, but some component of women's underrepresentation is caused by factors other than this (e.g., discrimination, personal preferences).I mean this to be evidence against a genetic explanation of under representation.
Come on. I know you know better than to draw statistical conclusions from a single event with a sample size of 11. So why do it?
Performances like this are more the norm now than ever, but the main reason is that the counterexample is such an extreme outlier that it blows a hole in the gaussian theory of distribution explanation for female under-representation.
They are also strongly correlated with various life outcomes in a manner which more or less corresponds to our intuitive intuition about the idea of "intelligence".
The Terman study of the gifted missed both future Nobel Prize winners in their sample.
The methods used to 'validate' IQ tests are not at all sufficient for equating their results with intelligence, or for arguing that it represents an immutable, genetic, predisposition of groups.

A: I'd find nothing easier. (You left out the dirty hippyprogressive Montessori school where they taught me Pirandello and Diderot.)
Q: Very good. (It didn't fit the rhythm, and anyway they get the picture.) How would you react to the idea that a psychological trait, one intimately linked to the higher mental functions, is highly heritable?
A: With suspicion and unease, naturally.
Q: It's strongly correlated with educational achievement, class and race.
A: Worse and worse.
Q: Basically nothing that happens after early adolescence makes an impact on it; before that it's also correlated with diet.
A: Do you work at the Heritage Foundation? Such things cannot be.
Q: What if I told you the trait was accent?
A: I'm sorry?
