A big black-white difference in a gene affecting the immune system

This new study looks at genetic differences in black and white women that affect immune system response. The top hit the researchers identified was a genotyped variant rs2814778, which is called the Duffy-null allele. 66% of black women carried the CC variant; 29% had the CT and 5% had the TT genotype. Compare this to white women: 100% of them have the TT genotype.

Now, the "experts" tell us race is not real. For example, they tell us that, say, whites differ among themselves much more than they differ from blacks. But look at this study: there is ZERO variation among whites, black women are fairly uniform too, and where they differ among themselves, it is due to having varied amounts of white ancestry.

It is widely thought that this geographic genetic diversity is the result of a strong positive selection for protection from malaria infection found in West Africa thousands of years ago. Blacks have faced different environments over tens of thousands of years, so what kind of researcher would claim that any genetic differences between blacks and other groups would be minimal or unimportant? Being able to survive malaria is pretty damn important, and the magnitude of the black-white difference in rs2814778 speaks for itself. The kind of researcher who would minimize and dismiss this is a dishonest researcher.
