A total of 589 compatible mating couples could be investigated against 432 incompatible mating couples in order to determine the selective mechanism operating on ABO blood groups. There appears to be no striking difference in the proportion of childless couples between the two groups. The mean number of living children presents a significant difference. There is 21% deficiency of 'A' children in the two groups. Similarly, there is 16% deficiency of 'B' children in the two groups. It appears that there is 31.9% fetal wastage in incompatible matings as compared with 17.15% in compatible matings.
为了确定作用于ABO血型的选择机制，共对589对相合配偶与432对不相合配偶进行了调查。两组中无子女夫妇的比例似乎没有显著差异。存活子女的平均数量存在显著差异。两组中“A”型子女均有21%的不足。同样，两组中“B”型子女均有16%的不足。与相合配偶的17.15%相比，不相合配偶的胎儿流失率似乎为31.9%。
