South Asian Genetic Landscape

Explore the genetic diversity and population structure across the Indian subcontinent. Discover how ancestral components vary across castes, tribes, and regional populations.

ANI Component

Ancestral North Indian - Related to populations from the Pontic-Caspian steppe and ancient Middle Eastern farmers. Higher in upper castes and northern populations.

Shown in blue on map
ASI Component

Ancestral South Indian - Represents the genetic component related to ancient South Asian populations. More prevalent in southern India and Dravidian speakers.

AASI Component

Ancestral Ancestral South Indian - Hunter-gatherer ancestry similar to Andaman Islanders. Highest in tribal populations and some southern groups.

Key Research Findings
Caste Stratification:

Upper castes show higher ANI ancestry (60-75%), while scheduled castes have more balanced ANI/ASI proportions.

Regional Patterns:

North-South gradient exists with northern populations having higher ANI and southern populations having higher ASI ancestry.

Tribal Populations:

Tribal groups preserve the highest levels of ancient AASI ancestry, especially in Central and South India.
