Abstract

The adult man in Africa, unlike the average European man, can have a biological fitness exceeding that of this wife. Sociocultural factors allow, and indeed encourage, this state of affairs, which may have far-reaching genetic consequences. The male procreative superiority index (MPSI) of any man is easily worked out by dividing the total number of a man's children by the average number of children born to each wife. The country-wide mean MPSI for 3095 fathers contacted throughout Ghana was 2 . 03, indicating that the Ghanaian father on the average has twice as many children as the mother. The genetic consequences of this phenomenon are discussed, bringing out effects on such diverse genes as those for abnormal haemoglobins, twins, and extra digits. African anthropogenetics needs rethinking more on factual lines than on theoretical evolutionary concepts.

男性生殖优势指数(MPSI):非洲人类遗传学的缺失系数。
非洲的成年男子,与一般的欧洲男子不同,其生理健康程度可以超过这位妻子。社会文化因素允许,甚至鼓励这种状况,这可能会产生深远的遗传后果。任何男性的生育优势指数(MPSI)都很容易计算出来,方法是将男性子女总数除以每位妻子所生子女的平均数量。在加纳全国范围内,3095名父亲的平均MPSI为2。03,这表明加纳父亲的平均子女数量是母亲的两倍。讨论了这一现象的遗传后果,提出了对异常血红蛋白、双胞胎和多余手指等多种基因的影响。非洲人类遗传学需要更多地根据事实而不是理论的进化概念进行重新思考。
