"(OCA2*481Thr) is responsible for light pigmentation in North and Northeast Asian populations. This allele is correlated with a lower resistance to the stress of the sunburn (meaning fairer-skinned)." 意思就是这个数据越高，皮肤就越白（而且越容易晒伤）。
按照数据，我们可以发现皮肤颜色排名（从最白到最黑）在亚洲就是：蒙古人和西伯利亚人 > 日韩和沈阳汉人 > 北京和西安汉族 > 江浙/福建/长沙汉族 > 广东汉族。也就是广东人最黑，蒙古人最白。
