You are incorrect. This is called Lewontin's fallacy which has been taught as fact across academia and pop science since the 70s with glee by people who believe it disproves "racism", but modern genetics prove it was totally wrong.
>Parents share approximately 50% of their DNA with their biological children
This is technically not true. A parent passes on 50% of their DNA, but they share over 99.9%, since 99.9% of the DNA of the other parent is the same as their own and passed to their child also.
White people and black people share about 99.9% of their DNA. The remaining 0.1% determines skin color, afro or straight hair, lactose tolerance et cetera.. These 0.1% are the genes we are talking about when we look at genetic distance.
>0.1% sounds small!
We share around 99% of our DNA with Chimpanzees and most of these genes influence things like cellular biochemistry, not traits that differentiate between people. Note it only takes 1 gene to give someone cystic fibrosis or sickle cell anaemia, one single gene can change someone's life. Do I really have to explain something so basic?
We see this represented on these genetic distance maps, which are multifocal and far more accurate than the cherry picked one Lewontin used in the 1970s long before we had sequenced the human genome. We can see that population groups largely separate for 10000s of years share clusters of genes, as you would expect. Likewise other groups have a different cluster of genes. When you compare these clusters, a German has far more in common with an Englishman than someone half-black half-white.
OP pic says specifically
>more genetically related
This is not incorrect, 99.99% is closer to 100% than 99.95%, is it not?
