Urea-starch-gel electrophoresis of casein samples from women of the Kikuyu tribe (central Africa) shows that this Negroid population had the same alpha- and beta-casein polymorphic pattern as Caucasoids, though their gene frequencies for the beta-locus were inverted. A new beta-casein variant (named beta-E) was identified.
对来自基库尤部落（非洲中部）女性的酪蛋白样本进行尿素淀粉凝胶电泳分析表明，尽管该黑人种群β位点的基因频率与白种人相反，但他们的α-和β-酪蛋白多态性模式与白种人相同。一种新的β-酪蛋白变体（命名为β-E）被识别出来。
