ABO、MN血型及其与测量体征关系的初步探讨

A PRELIMINARY APPROACH TO THE RELATIONS BETWEEN THE BLOOD GROUPS AND THE ANHTROPOMETRIC VARIATION

本文提供了男、女两性共404人ABO、MN血型各表现型的35个体质特征测量数据,对血型和测量体征的关系进行了初步讨论。统计分析表明,不同血型群体的某些单个体征平均值之间有显著差异。对所调查的35个体征作整体分析,可见男性MN系统和女性ABO、MN系统各血型群体平均值之间差异显著。在MN血型系统,MN型群体的测量体征平均值低于M型和N型与MN基因型的杂合状态有密切关系。本文还分析了4个民族的血型资料,表明MN血型在ABO血型系统是随机分布的。

This paper presents the results of an examination of phenotypes within two blood group polymorphisms to determine the effect, if any, of blood groups on anthropometric traits.The examination is based on the data obtained from 404 subjects. All the subjects, belonging to Li nationality, are enrolled middle school students and the students at Guangdong College of Minorities. ABO, MN blood groups were determined and 35 features were simultaneously surveyed for all the subjects. The distributions of MN blood types in the ABO blood group system were also examined in this paper.It is clear by statistical analyses that blood group phenotypes show some noticeable differences with regard to average values of anthropometry. Judging from 35 physical traits as a whole, there exist significant differences among the blood group phenotypes, since the Xp (2df) s are less than 0.05 by rank order analysis. We may infer, in terms of our study only, that some correlations exist between blood group phenotypes and anthropometric traits. In MN system, the most striking feature about the results is the consistency of lower total rank in the samples of MN phenotypes for both males and females. It is deduced on account of the allelic equivalence of the gene M and N that the lower anthropometric measurements of the MN phenotype are related to the MN heterozygote. In ABO system, the significance of the results is clouded by our inability to distinguish, for A and B, the hemozygotes from the heterozygotes. We have made use of t test to compare the distributions of MN blood group phenotypes in the ABO blood group system. The results show that they are not related to ABO groups. It is concluded that no hereditary relation exists between MN system and ABO system, that is to say, MN blood group factors are hereditarily independent from ABO factors. This conclusion is identical with that established by other authors.
