Indian Community DNA Data

Understanding Indian Community Genetics

India's unique social structure, with its history of endogamy (marrying within one's community), has created distinct genetic signatures for different communities. Over thousands of years, practices like caste endogamy, regional isolation, and community-specific marriage patterns have led to measurable genetic differences between groups—even when they live in the same geographic area.

Modern DNA testing can now identify these community-specific patterns with remarkable accuracy. By analyzing haplogroup frequencies, autosomal DNA markers, and IBD (Identical By Descent) segments, geneticists can trace the ancestral origins and migration histories of India's diverse communities.

What the Data Reveals

Haplogroup frequencies provide a window into ancestral origins. Communities with higher R1a-Z93 frequencies typically have more Steppe (Indo-Aryan) ancestry, while those with higher H-M69 or L-M20 reflect deeper South Asian roots. However, every community is a mix—there are no "pure" genetic groups.

Note: All data is based on peer-reviewed genetic studies. Individual results may vary significantly from population averages.
