ABO、MN血型及其与测量体征关系的初步探讨

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。

ABO血型的遗传平衡问题解析

人类控制ABO血型的基因座位上的等位基因频率的估计是相当棘手的问题.在遗传学著作、教材和教学中,群体遗传平衡相关估算中常出现"循环论证",这一问题需要深入分析.从根本上讲,ABO血型遗传平衡估算问题的困难来自2个等位基因对第3个的完全显性.在实际中.人类大群体中的ABO血型一般是平衡的,因此可用r=(-O)1/2、q=1-((-A) (-O))1/2和p=1-((-B) (-O))1/2近似地求基因频率.

Frequencies of ABO, Rh and Kell phenotypes in couples from Han, Kazak, Uyghur and Hui in Xinjiang: an inheritance simulation model for blood group incompatibility in new-born

The Xinjiang region with residents from more than 13 minorities represents an area of many diverse ethnicities. This ethnic diversity in relation to their blood groups and immune status may have a consequential impact on the clinical status of married couples. To evaluate the risks of haemolytic disease in new-born infants, we investigated the rate of blood-group incompatibility among 487 married couples from four ethnic minorities, namely the Han, Hui, Uyghur and Kazak populations. Han minority married couples showed significantly different ABO, Rh and K phenotype frequencies between marrial relationship, whereas there was no significant difference in ABO, Rh and K phenotypes between the Uyghur, Hui and Kazak .There was a significant difference between ABO blood types in Han married couples, in the Kazak Rh-C phenotype and in the Uyghur Rh-D phenotype. The Hui married couples only demonstrated ABO, Rh and K phenotypes. The Hui minority showed the highest incompatibility rate for Rh-C and Rh-E phenotypes between mothers and their new-born infants. The highest incompatibility rate for the ABO phenotype occurred in the Kazak group. These results particularly demonstrate the clinical issues relating to ABO and Rh incompatibility, in the Kazak and Hui minorities, respectively.

Distribution of ABO blood groups and incidence of Rh factor (D) in various ethnic groups in the Hindu Kush region (Kafirs, Kalash Chitrali)

With the aid of Eldon cards the distribution of the ABO blood groups and of the Rh factor (D) was investigated in different native ethnic groups (Kafirs, Kalash, Chitrali) in the Hindu Kush region of Afghanistan and Pakistan. All studied groups are characterized by a relatively high frequency of blood group gene A and extremely low frequencies of B and O. This distribution differs appreciably from that of the rest of the Indian subcontinent as well as that of the adjacent Central Asiatic areas. The possible causes of the exceptional position of the native Hindu Kush groups in the ABO blood group system are discussed. It may be assumed that selection as a result of mother-child compatibility played a role as will be shown in a later paper. Concerning the studied traits of the Rhesus system, all investigated groups fit in the range of variation of the South Asian area.     

Structural analysis of the correlations of genetic markers with physiological indices

The structure of phenotypic and genetic correlations between ABO blood groups, MN, Rh(D), haptoglobins and concentration indications of the total cholesterol, of sugar curve, the levels of systolic and diastolic arterial pressure was studied in twins by the method for cluster analysis (121 monozygotic twin pairs, 120 dizygotic like sex twin pairs and 107 pairs of unlike sex twins). No correlation between the systems analysed and their indications on the phenotypic level was observed. By analysis of genetic correlations, the existence of correlations between the Rh system and arterial pressure, and the total cholesterol concentration, as well as between the ABO system and sugar concentration indexes, was established. Possible genetic causes for correlations obtained are being discussed.
