I’ll let someone else’s link (ironically trying to argue with me) do the talking:

In animals and plants, binary sex is universally defined by gamete type, even though sexes vary in how they are developmentally determined and phenotypically identified across taxa.

Real biologists saying real facts. Incidentally, I don’t really get the point of histrionics like “I’m done” or another commenter calling facts “boring”. I guess that maybe works for twitter clapbacks where vibes are more important than facts? When you’re ready though, the scientific truth will still be there for you.
