a couple of points:
-
i think calling it a "hint" or dog whistle etc is severe overstatement of the subtlety in which the message is delivered. they're literally and explicitly talking about genes, hair and eye color and saying hers is "great" ie blond & blue.
-
i don't know why no one points to the actual bad part which is them saying genes determine personality, which is straight up eugenicist bullshit
