Killer immunoglobulin like receptor gene content diversity among Northern Indian population
KIR frequencies and profiles of northern Indians were more similar to Western Eurasians, Africans and Asian Indians. This may suggest that KIR genes are under constant evolutionary pressures and selection, which may be linked to different invading pathogens
Paleolithic spread of Y-chromosomal lineage of tribes in eastern and northeastern India
The study suggested that the majority of the male gene flow of Austroasiatic tribes occurred during the late Pleistocene period. The results suggest gene flow from Southeast Asia to Northeast India, albeit more significantly among Tibeto-Burman than Austroasiatic-speaking populations
Alu Polymorphic Insertions Reveal Genetic Structure of North Indian Populations
The Indian subcontinent is characterized by the ancestral and cultural diversity of its people. Genetic input from several unique source populations and from the unique social architecture provided by the caste system has shaped the current genetic landscape of India. In the present study 200 individuals each from three upper-caste and four middle-caste Hindu groups and from two Muslim populations in North India were examined for 10 polymorphic A…
Presence of three different paternal lineages among North Indians: A study of 560 Y chromosomes
The results revealed that a substantial part of today's North Indian paternal gene pool was contributed by Central Asian lineages who are Indo-European speakers, suggesting that extant Indian caste groups are primarily the descendants of Indo-European migrants. The presence of haplogroup E in Shias, first reported in this study, suggests a genetic distinction between the two Indo Muslim sects. The findings of the present study provide insights in…
Effect of Sociocultural Cleavage on Genetic Differentiation: A Study from North India
Indian populations possess an exclusive genetic profile primarily due to the many migratory events, which caused an extensive range of genetic diversity, and also due to stringent and austere sociocultural barriers that structure these populations into different endogamous groups. In the present study we attempt to explore the genetic relationships between various endogamous North Indian populations and to determine the effect of stringent social…
North Indian Muslims: Enclaves of foreign DNA or Hindu converts
The mtDNA composition of two Muslim sects from the northern Indian province of Uttar Pradesh, the Sunni and Shia, have been delineated using sequence information from hypervariable regions 1 and 2 (HVI and HVII, respectively) as well as coding region polymorphisms. A comparison of this data to that from Middle Eastern, Central Asian, North East African, and other Indian groups reveals that, at the mtDNA haplogroup level, both of these Indo‐Sunni …
Microsatellite Variation at 24 STR Loci in Three Endogamous Groups of Uttar Pradesh, India
We have studied variation at 24 microsatellite markers among 50 individuals from each of three endogamous groups, Bhargavas, Chaturvedis, and non-Bhargava, non-Chaturvedi Brahmins of Uttar Pradesh, India. The number of alleles at the loci tested varied from 4 to 11, with an average of 6 at each locus. Heterozygosity was found to be quite high at all loci in the three subpopulations. It varied between 0.44 to 0.84 among Bhargavas (average 0.6510),…
Surname Endogamy among the Brahmin of India
Endogamy has been a strong influence on Hindu society over the centuries and most of the 75,000 subcastes or subgroups of India's complex social stratification system practise endogamy, while the further divisions within these subcastes, called gotras, are required to marry exogamously. The present study focuses on three socioculturally isolated, highly endogamous groups, to study the effect of endogamy on genetic microdifferentiation. The groups…
