✦ Synopsis

For the study of group specific component (Gc) and phosphoglucomutase (PGM1) polymorphism, isoelectric focusing was performed on eleven tribal and non-tribal populations of Himachal Pradesh, India. They were chosen to illustrate interregional and intraregional variations. The subtype frequencies of these two systems showed clear differences in the genetic constitution of these populations of Himachal at both levels. There is a large increase in the mean heterozygosity (H) for each system by isoelectric focusing over that shown by electrophoresis. Discriminant and distance analyses both suggest that the subtype frequencies provide greater potential for the study of genetic diversity among populations. The data on these additional alleles found by isoelectric focusing are examined for some of their genetic and anthropological implications.
