I've posted it elsewhere in the thread already, but this article is a good recap of research on the topic : https://www.psychologytoday.com/blog/rabble-rouser/201707/wh...
How very ironic you should say that, given the author's interesting demonstration (with figures) in that very same post of the propensity of the other side to over-cite weak studies that fit the desired narrative, and under-cite inconvenient ones with orders of magnitude better sample sizes and methodology.

There are lots more but here are a few:

Yes, I think individual variation is the key here.
I know quite a few girls that didn't like to do activities things meant for girls and the same for quite a few boys. No matter how much pressure (from parents, teacher and peers) they received they just followed their nature and did whatever they liked more (e.g. the girls played soccer and the boys "played tea"). I have examples of that from my experience both as a child and now a parent and uncle.
Wouldn't this mean that perhaps there is something in the tendencies and predisposition that is not rooted in social coercion?
Often when people think about biological cause they think in terms of what a male or female brains should be, just by virtue of being labeled a male or female biologically (e.g. by some physical quality, including tests involving chromosomes)
But what if you, as an individual just don't match?
Does that make your abilities or tendencies less hereditary or less caused by biology?
The biology of the individuum is what affects the individuum, along with upbringing and literally everything else, including others prejudices!
Personally, a big advantage of this current wave of reverse bigotry is that individuals who would have been just put aside without even giving them a chance now can fare better because society e.g. is being trained at the fact that women can be just as good.
Often, that's what matters. I often hear that the end justifies the means; that if we actually try to have a nuanced conversation about this complex topic we'd just give misogynists and xenophobes a way to pursue their agendas.
And we definitely need more work if we want that people have less bias when confronted with a person of a gender that "doesn't match".
I wonder when will come the time that being fully open, objective and honest will be the most practical way of achieving this goal.
I'm sure there have been studies on these topics though, and I think that's what your parent comment is asking for?!
Although, making these out to be biological differences could be a stretch.
