All mainstream South Asians are a mixture of three major ancestral components: Steppe_MLBA, IVC (Indus Valley Civilization-related) and AASI/SAHG (South Asians Hunter Gatherers also called Ancient Ancestral South Indian). Researchers use Onge or AHG (Andamanese Hunter-Gatherer) as proxies for AASI. The IVC-related ancestry itself is an earlier mixture of Iranian farmer-related ancestry and SAHG/AASI, after which Steppe_MLBA ancestry mixed with IVC-related populations to form the ancestry found in many present-day South Asians. | All mainstream South Asians are a mixture of three major ancestral components: Steppe_MLBA, IVC (Indus Valley Civilization-related) and AASI/SAHG (South Asians Hunter Gatherers also called Ancient Ancestral South Indian).

These three ancestral components are found in almost all mainstream South Asians, but in different proportions. Every caste and community has its own typical range of these ancestry components, although these ranges often overlap with those of other castes and communities. | These three ancestral components are found in almost all mainstream South Asians, but in different proportions.

! # !! Component !! Mainly Associated With | |||
|- | |||
| 1 || '''Steppe_MLBA''' || Late Bronze Age steppe pastoralist populations (Sintashta/Andronovo-like), Indo-Iranian/Indo-European–linked movements into South Asia in the 2nd millennium BCE, and a substantial part of the ancestry of many Indo-Aryan–speaking and some higher-caste groups. These people are credited to have likely brought the Indo European language family into South Asia. | |||
|- | |||
| 2 || '''IVC''' (Indus-related / Indus Periphery) || People of the Indus Valley Civilization and surrounding regions, a mixture of Iran-related early farmer ancestry and South Asian hunter-gatherers, and the largest single ancestral layer feeding into both ANI and ASI-rich populations across South Asia. | |||
|- | |||
| 3 || '''AASI''' (Ancient Ancestral South Indian) || The local, native South Asian hunter gatherer ancestry that predates farming and steppe migrations and contributes substantially to many present day South Asian groups. | |||
|- | |||
| 4 || '''AHG''' (Andamanese Hunter Gatherers) || A proxy source based on Andamanese genomes representing AASI like (native South Asian hunter gatherer) ancestry in qpAdm models, used to approximate the indigenous Indian component in studies such as those by Lomous Kumar. | |||
