I mean, Hazel mom was black and Hades was in a white form but Hazel is referred to as full-blooded African-American.

So, does race not transfer?

But, wait, Percy and Annabeth are near replicas of their immortal parents in appearance (same eye color, hair color, build, etc.). If all that can transfer in genetics, why not race?

For example, if Thanatos (who is black in his appearance in the series) had a child with a white woman, would the child be full blooded white, full blooded black or a mix? There doesn't seem to be any "mixed" children of the gods except for Piper's who is only called that because her father was already mixed. Do we need to assume that gods just transform into the same race of their romantic interest every single time or is there something really weird about how race transfers into demigod children?

Also, do you believe immortal gods' DNA to be dominant for the most part? I'm inclined to think that as every half-blood (that is the same race as their immortal parent) seem to look like identical copies (Annabeth and Percy) or very similar (Nico, Clarisse, Will etc).
