Netflix version of Bill Nye episode omits segment about biological basis for sex

[Geremia]

Omitted:
"I'm a girl," a young woman said in the original episode. "Could have just as easily been a boy, though, because the probability of becoming a girl is always 1 in 2. See, inside each of our cells are these things called chromosomes, and they control whether we become a boy or a girl. See, there are only two possibilities: XX, a girl, or XY, a boy."

Of course, we can't explain actual science to the children.  Gets in the way of social warfare, donchaknow?
