Have you done any research into the comparison between the genomes of chimpanzees, gorillas etc. as compared to humans. They are genetically very close to us. What about the genomes of humans versus bananas. If you go and find out, you might be surprised at how close we are genetically to them, (ie. we're more banana-like more than you might think).
I'd say that the African race, and other races are pretty well identical, except in some very minor ways. Sure, we might have different skin colours, and facial features, but as a society, we need not give that a rat's patooty of significance. Essentially we're the same.
Magilla.
It depends on what is being compared.
For example:
http://eugenes.org/all/hgsummary.html
^^^^^Humans have 29529 homologue genes in chimpanzees. The total compared is 33860.
Whatever comparison mode is used, all lifeforms share a portion of genes.
Comparing one human to another human would give a 100% homologue.
Then, you can compare the gene versions and you would also have to figure out what each gene does, or whether what they do together, how one effects the other. At that point, it becomes complicated.
Apparently, caucasians have some neanderthal genes. There was an article about this:

Quote:Previous studies, mainly on people of European ancestry, found that individuals carrying a particular segment of DNA had a 20% lower risk of developing a critical COVID-19 infection.
According to the research, this DNA segment encodes genes in the immune system and is inherited from Neanderthals in about half of all people outside Africa.
but, most Africans have the same genes
Quote:The researchers found that individuals of predominantly African ancestry had the same protection as those of European ancestry, which allowed them to pinpoint a specific gene variant of particular interest.
The analysis included a total of 2,787 hospitalized COVID-19 patients of African ancestry and 130,997 people in a control group from 6 cohort studies. 80% of individuals of African ancestry carried the protective variant. The outcome was compared with a previous, larger metastudy of individuals of European heritage.
Quote:According to the researchers, the protective gene variant (rs10774671-G) determines the length of the protein encoded by the gene OAS1. Prior studies have shown that the longer variant of the protein is more effective at breaking down SARS-CoV-2, the virus causing the disease COVID-19.
