The breast area can also show cromosome variations, as well as the testicles. I'm no expert but here is a source among probably many others: https://www.livescience.com/27248-chromosomes.html |
Well yes, our genes dictate our phenotype. Still, just by looking doesn't always give us complete insight into genotype since the environment can also influence someone's phenotype. The genotype-phenotype link isn't one to one.

I mean, that is largely my point. You can't assess the entirety of biology based simply on phenotypic variation. To do so is "convenient" but it is far from accurate. That is why I don't really like the phrase "biological female". It is a convenient simplification of biology to use that as a synonym for "someone born with a vagina", but we should still recognize that the two statements do not mean the same thing, despite that convenience. |
Well a great many people like convenience and for convenience's sake, biological female means "born with a vagina". It's that simple. In a majority of instances in the day-to-day, hormone levels or genetic variations aren't going to come up and play a role.
But hey, if you wanna bust out the blood tests every time you want to assess someone's sex, who am I to stop you?
