"the lines aren’t drawn along genetic lines. " Race is definitely drawn along genetics lines - you've just demonstrated that in your example. The 1/4 black - 3/4 white person was not identified as 'Asian' in your example, but rather, in the mixed physical scenario was crudely categorized as one or the other, in the example you gave, Black. (FYI I tend to disagree a bit about the category though: I believe people will be categorized mostly for how they actually look, not so much the 'ratio' of anything. There's a lot of 1/2 Filipino 1/2 White people on TikTok who 'look' 100% White and make funny videos about the fact nobody believes them about their heritage). Your example shows that race is definitely a social construct, but that it also has underlying genetic realities.
