But there’s a very good reason I never expected there to be recent selection driving this anyhow: Australian Aboriginals sometimes manifest blonde hair, and the best genetic data suggests separation from Melanesians of at least 10,000 years.Additionally, the Solomon Islands were not part of Sahul, so that’s a conservative estimate.Another aspect of the phenotype was also straightforward: it did not seem that light hair color resulted in any concomitant lightening of the skin.Granting that this was a heritable biological trait, the questions then were simple: was this trait an independent occurrence of de-pigmentation in Oceania, or was it due to introgression of European alleles?What I am suggesting then is that this pigmentation mutation is an old feature of the Oceanian populations, on the order of tens of thousands of years.That is why there isn’t LD around this region; any LD which existed was long ago eliminated by recombination.Those individuals who are homozygotes tend to have blond hair, while those who are not tend not to have blonde hair.

This missense mutation is predicted to affect catalytic activity of TYRP1 and causes blond hair through a recessive mode of inheritance. They looked at variants in a lot of people with the trait, vs. Additionally, if you check the supplements and read the text it’s obvious there is no population straification.

If the drift event occurred in the past, the allele should be fixed, or, it should be extinct.
