We describe the gene frequency distributions for 29 different blood group, serum, and erythrocytic proteins for three Mennonite communities from Kansas and Nebraska and compare their gene frequencies with those of Amish, Hutterite, and Mennonite populations using the topological method of Harpending and Jenkins (1973). Subdivision of these communities into congregations reveals that the "fission-fusion'h model best characterizes the relationship between the genetic patterns and historical events. These Mennonite populations, although reproductively isolated at the turn of this century, are presently entering the mainstream of US rural culture.
我们描述了堪萨斯州和内布拉斯加州三个门诺派社区29种不同血型、血清和红细胞蛋白的基因频率分布，并使用哈彭丁和詹金斯（1973年）的拓扑方法，将它们的基因频率与阿米什人、哈特派和门诺派人群的基因频率进行了比较。将这些社区细分为不同的教会发现，“裂变-融合”模型最能描述遗传模式与历史事件之间的关系。这些门诺派人群，尽管在本世纪初处于生殖隔离状态，但目前正融入美国乡村文化的主流。
