Dark skinned people from Asia are from a different race than dark skinned people from Africa. For example if you have a dark skinned person with epicanthic fold, chances are that's a person from Indonesia or its whereabouts. Race is not ONE trait, it's a set of traits, and all of them are encoded in DNA.

> dark skinned person with epicanthic fold, chances are that's a person from Indonesia or its whereabouts. Or South Africa, or east Africa, etc. Or since we're talking about people and not geographic features, we could be talking about a person in the e.g. Americas who is the product of many "origin" regions of the world. > Race is not ONE trait, it's a set of traits, and all of them are encoded in DNA. The problem is the "set of traits" is squishy and often defined in the moment. This, plus the importance we assign to race in all affairs, has led many societies to try to codify what is meant by race. Racial distinctions are different in the context of different communities (e.g. in the US it's very important to know who is "black" vs who is not). For example, in the US we long practiced the One-drop rule [1], which lead to absurd racial classifications [2] that required you to know a person's entire ancestry back 3 or 4 generations in order to identify her race (obviously, this is recursive). The trouble is we start from a position of knowing how we want to classify a person, by seeing them or knowing where they come from ("I know she's black, so my classification scheme needs to ensure she's black."). We then need to apply tools (one-drop rule, etc.) to make sure that person fits the classification. Gene clusters are a clumsy way to accomplish the same thing using modern tools. Obviously some populations share some traits. But saying "race" is something that can be objectively identified for every given individual is naive. Back to your original point -- there's no such thing as the "last few genes" that make a person black. That's approximately like saying the last few quanta of pigment in a person's skin change their race. Or that a person's race can be determined by calipers [3]. It's ridiculous. 1 - https://en.wikipedia.org/wiki/One-drop_rule https://en.wikipedia.org/wiki/One-drop_rule 2 - https://en.wikipedia.org/wiki/Quadroon https://en.wikipedia.org/wiki/Quadroon 3 - https://en.wikipedia.org/wiki/Phrenology https://en.wikipedia.org/wiki/Phrenology
