Phenotype and gene frequencies for four blood group systems (ABO, MN, Rh and P) and haptoglobin among five endogamous groups of Delhi, India, are reported. All the systems are polymorphic in all the population groups. The average heterozygosity per locus in high (in the range 48-52 per cent) for all the groups. The extent of genic variability among the groups in terms of net codon differences per locus has been studied; the heterogeneity within the groups is large as compared to the between-group heterogeneity. There is no definite clustering of the of the groups with respect to their biological rank.
报告了印度德里五个内婚群体中四种血型系统（ABO、MN、Rh和P）以及触珠蛋白的表型和基因频率。所有系统在所有群体中均为多态性。所有群体每个基因座的平均杂合度较高（在48%-52%范围内）。已研究了各群体间每个基因座净密码子差异方面的基因变异程度；与群体间异质性相比，群体内异质性较大。各群体在生物学等级方面没有明确的聚类。
