Only 7 nonrare haplotypes concerning Y-chromosome-specific TaqI fragments recognized by DNA probes p49f and p49a were encountered in 433 individuals belonging to 7 populations living in central Africa. Most of the haplotypes (77.7%) are characterized by the allelic combination A1,C0,D0,F1,I1 (haplotype IV). The degree of variability displayed by these sequences is low in the African population studied, compared with Europeans, probably because of the recent common origin of the Bantu-speaking populations studied and the common practice of male polygamy in Africa.
在居住于中非的7个群体的433名个体中，仅发现了7种与DNA探针p49f和p49a识别的Y染色体特异性TaqI片段相关的非罕见单倍型。大多数单倍型（77.7%）的特征是等位基因组合A1、C0、D0、F1、I1（单倍型IV）。与欧洲人相比，在研究的非洲人群中，这些序列显示出的变异程度较低，这可能是因为所研究的讲班图语的人群起源较近，以及非洲男性一夫多妻制的普遍做法。
