In northern India, the Multan-based Langah Sultanate and the Kashmir Sultanate were established during the 14th century. Nobles in the court of the Delhi Sultanate founded other Islamic dynasties elsewhere in India including Khandesh Sultanate. The Kingdom of Rohilkhand was also a major power in northern India in the 18th century.
The Greeks in India even seem to have played an active role in the propagation of Buddhism, as some of the emissaries of Ashoka such as Dharmaraksita, [46] or the teacher Mahadharmaraksita, [47] are described in Pali sources as leading Greek ("Yona", i.e., Ionian) Buddhist monks, active in Buddhist proselytism (the Mahavamsa, XII).

Companies were later also able to use this data to estimate how much of each ethnicity a customer has. FamilyTreeDNA entered this market in 2010, followed by AncestryDNA in 2012, and the number of tests grew rapidly. By 2018 autosomal testing had become the predominant type of test, and for many companies the only test they offered. [16]
Cordeaux et al. (2004), based on the spread of a cluster of haplogroups (J2, R1a, R2, and L) in India, with higher rates in northern India, [247] argue that agriculture in south India spread with migrating agriculturalists, which also influenced the genepool in south India.
Genetic studies on the Sinhalese are part of population genetics investigating the origins of the Sinhalese population. All studies agree that there is a significant relationship between the Sinhalese and the Bengalis and South Indian Tamils, and that there is a significant genetic relationship between Sri Lankan Tamils and Sinhalese.
Test results can be retrieved within 7–14 days after the test is done. This method is 99.4% accurate at detecting and diagnosing fetal chromosome abnormalities. There is a slight risk of miscarriage with this test, about 1:400. Another method of prenatal testing is chorionic villus sampling (CVS). Chorionic villi are projections from the ...
According to Arunkumar et al. (2015), Y-chromosomal haplogroup O2a1-M95, which is typical for Austroasiatic speaking peoples, clearly decreases from Laos to east India, with "a serial decrease in expansion time from east to west", namely "5.7 ± 0.3 Kya in Laos, 5.2 ± 0.6 in Northeast India, and 4.3 ± 0.2 in East India".
Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct , and that using it as a proxy for genetic differences among populations is misleading.
