RE: ... there are clearly quantifiable differences between individuals associated with their genetic origins. This is well known in all biological scientific fields: medicine, forensics, pharmacology

  This point falls apart with "mixed-race" individuals. People have mixed since the dawn of man. The real conflict is cultural.

No, I disagree. Colors can be mixed together, so does that mean that the color blue does not exists? Can you point me where exactly blue starts and ends on a rainbow? Let's go even further, and take two mixed colors - purple (blue+red) and lime (green+yellow) - they're both mixed, so does that mean that there is no difference between those two? This is a fallacy. People might've mixed, but it doesn't make everyone the same. This is blatantly false. In the actual reality you just inherit some traits from one parent and some from the other. I'm not denying cultural differences obviously, but it does not contradict anything, it's just how genetics work. Race is just a superset of ethnicity, and it's more fuzzy around the edges.

Respectfully, mixing colors in lifeforms is not as binary as "purple (blue+red) and lime (green+yellow)". A black rose and a white rose does not produce a gray rose. A black cat and a white cat will not give gray cat. Two black dogs can give you a gray dog with blue eyes.

If each color represents a particular heritable trait then it's more or less like that.
