>>12664111that's cause of ANE (ancient north eurasian) admixture, the people that blond hair genes come from
russians don't have them at the same amount but they look similar to them because of similar environment. People with the most ane admixture look siberian, and ANE was mongoloid looking
>>12664112yeah all you need is just the genes and you have the chance to have blond hair
if the environment is favorable then you have way more chances but even some levantines get blond hair from time to time
