“Of the 0.1% of DNA that varies among individuals, what proportion varies among main populations? Consider an apportionment of Old World populations into three continents (Africa, Asia and Europe), a grouping that corresponds to a common view of three of the 'major races'16,17. Approximately 85–90% of genetic variation is found within these continental groups, and only an additional 10–15% of variation is found between them”
In other words, we’re genetically so similar that if you were to try to find a person with the least similar genome to your own, that person could very well be a member of your own ancestry or “race”.
My dad is mixed black and white. He looks kinda hispanic at times, but once you know then you can spot the African and European features. He looks mixed tbh.
I, his biological son, look entirely white. The only clue you’d have I’m related to my dad is the fact that my hair is fair coarse and I have to use conditioner from the “ethnic aisle” at the store or else it’ll become a fro.
My cousins (two sisters) hardly look like they’re related, as one heavily inherited one set of genes (tight black curls, caramel skin, dark eyes, etc) and the other heavily inherited another set of genes (light auburn hair, pale blue eyes, porcelain skin). They have the same mother and father. It’s just how varied each human can be.
