A non-Amish "Pennsylvania Dutch" semi-isolate was found to have a high frequency of Tay-Sachs gene. This high frequency could be ascribed to founder effect and may represent, in microcosm, how this mechanism could have produced the high gene frequency among Ashkenazi Jews.
人们发现,一个非阿米什人的“宾夕法尼亚荷兰人”半隔离群体中,泰-萨克斯基因的频率很高。这种高频率可能归因于奠基者效应,并且在微观层面上可能代表了这种机制如何在德系犹太人中产生高基因频率的。
