Neo-Nazis who espouse the "Great Replacement Theory" could use a crash course in Genetics, as it largely proves them wrong.

To begin with: what is the "Great Replacement Theory"? In short, it is a belief peddled by bigots that Jewish people are conspiring to breed the White Race to extinction by convincing white people to have children with non-white people.

Not only is such a belief malignantly evil; it is also patently erroneous. This is because in the absence of selective evolutionary pressure, allele frequency in a population largely remains unchanged from one generation to the next.

Let's unpack that genetic dictum. An allele is a part of a person's genotype. That means it is coded into their DNA. It is responsible for creating a person's phenotype, which is the physical expression of those genes. So if a person has enough of the alleles for blue eyes, their phenotype will be blue eyes.

According to long-standing genetic theories, there are only three things that change an allele's frequency within a population: Sexual Selection, Natural Selection, and Genetic Drift.

Sexual Selection means a certain trait is considered more or less sexually attractive, causing it to grow or decline within a population. The last time I checked, blue eyes are not considered ugly. So they will not decline as a result.

Natural Selection means a trait is either more or less conducive to survival. This would cause it to either proliferate or be decimated from one generation to the next. The last time I checked, having blue eyes does not make people more or less likely to survive, as it is purely a cosmetic trait.

Genetic Drift is the tendency for an allele to rise or fall over the course of thousands of generations, usually by pure happenstance. This would be just as likely to raise the number of blue-eyed people in the world as it would be to lower it from one millennium to the next.

So in conclusion: the white race will not be destroyed by intermixing with other races. The overall prevalence of blue-eyed, blond-haired people on Planet Earth will probably not decrease, and might even increase, as a result. That means all of the Neo-Nazis who are freaking out about interracial marriages can find some other triviality to devote their neuroticism to.
