Serological and biochemical investigations among five endogamous groups of Delhi, India

Abstract
Phenotype and gene frequencies for 4 blood group systems (ABO, MN, Rh and P) and haptoglobin among 5 endogamous groups of Delhi, India, are reported. All the systems are polymorphic in all the population groups. The average heterozygosity per locus is high (in the range 48-52%) for all the groups. The extent of genic variability among the groups in terms of net codon differences per locus was studied; the heterogeneity within the groups is large as compared to the between-group heterogeneity. There is no definite clustering of the groups with respect to their biological rank.
