Just googled hypertension link - top few results say links are inconclusive. they seem to be American research. No idea if they are peer reviewed or verified. One of the site actually said in the conclusion that environmental factors may have bigger contributions to hypertension than any genetic variation.
If you can point me in the direction of other disease you mentioned that has link to genetic variation it would be great. Thanks.
Also I think it is widely accepted amongst medical professionals blacks are more at risk to these diseases. But I am not sure it is accepted that their genetics are playing the part. Anyway I am happy to be proven wrong if that is the case.
The most famous example is sickle cell anaemia, in which genetics does more than play a part - it's
solely genetic. It's caused by variants of the beta globin gene. Variants that are almost non-existent in people whose relatively recent ancestry is from some parts of the world and present in over 40% of people whose relatively recent ancestry is from some other parts of the world. You can easily check that. It's well known and uncontested. Even the reason for the variation is well known - selection pressure caused by malaria. Which is why it has a
correlation with skin colour -the same environmental conditions that make malaria more of a risk also happen to make darker skin more likely.
There are many less famous examples. It's most definitely accepted that variations of genes play a part in the prevalance of some diseases and the severity of some diseases. It's most definitely accepted that genetic variants are
not uniformly distributed around the world. If they were, that would be excellent evidence for divine intervention because it wouldn't happen naturally.
