Urea-starch-gel electrophoresis was used to examine 175 casein samples, 130 collected at random from women from the urban area of Turin, and 45 from women resident in villages in the Sardinian hinterland. Two polymorphic systems controlling alpha- and beta-casein were demonstrated in both groups, together with similar gene frequencies for individual alleles. In addition, a rare variant was discovered in the Sardinian group.
采用尿素-淀粉凝胶电泳法检测了175份酪蛋白样本，其中130份是从都灵市区女性中随机采集的，45份是从撒丁岛内陆村庄的女性居民中采集的。在两组中均证实了控制α-和β-酪蛋白的两个多态系统，并且各个等位基因的基因频率相似。此外，在撒丁岛组中发现了一种罕见的变体。
