A serological study among two endogamous groups of chamars
Insights
Genetic analysis of Kureel and Jaiswar Chamars reveals distinct blood group frequencies. This study investigates the genetic impact of geographical isolation on these low-caste groups in India.
Area of Science:
- Anthropology
- Population Genetics
- Human Genetics
Background:
- The Kureel and Jaiswar Chamars are distinct caste groups in India, occupying the lowest rung of the social hierarchy.
- Geographical separation and isolation are common factors influencing genetic diversity within populations.
Purpose of the Study:
- To examine the genetic effects of geographical fission and subsequent isolation on two Chamar caste groups.
- To compare the ABO and Rh(D) blood group frequencies between the Kureel Chamars of Lucknow and the Jaiswar Chamars of Jaunpur.
Main Methods:
- Blood samples were collected from unrelated individuals from both groups.
- ABO and Rh(D) blood typing was performed on all collected samples.
- Statistical analysis was used to compare the observed frequencies.
Main Results:
- Significant differences in ABO and Rh(D) blood group allele frequencies were observed between the two Chamar groups.
- The genetic data suggests a measurable impact of geographical isolation on the populations.
Conclusions:
- Geographical isolation has led to detectable genetic differentiation between the Kureel and Jaiswar Chamar populations.
- The study highlights the role of isolation in shaping the genetic landscape of endogamous social groups.
Abstract:
On a sample of n = 320 unrelated Kureel Chamars (Lucknow district) and n = 314 unrelated Jaiswar Chamars (Jaunpur district) ABO- and Rh(D)-typings have been carried out. The two Chamar groups occupy the lowest position in caste hierarchy. In this paper the question is examined, whether the geographical fission of the both Chamar groups, followed by isolation, has had genetical effects.
