<!-- START OF : div id="storytext"--><!-- more than 4 paragraphs -->WASHINGTON: A genetic search of India's diverse populations shows most people there have mixtures of European and ancient south Indian genes, and helps illustrate the deep roots of the country's caste system, researchers reported.
United States and Indian scientists took blood samples from 132 individuals from 25 diverse groups in India. They then unravelled the volunteers' genetic code, sifting through key areas of DNA for similarities and differences.
Two ancestral populations emerge, and their genes dominate the Indian genome, the researchers said in findings reported in the journal Nature.
'Different Indian groups have inherited 40 to 80 per cent of their ancestry from a population that we call the Ancestral North Indians, who are related to western Eurasians, and the rest from the Ancestral South Indians, who are not related to any group outside India,' said Harvard Medical School geneticist David Reich.
The paper says the role of endogamy, the term for marriage within a tribe or caste, in shaping India's DNA has deeper roots than many may think.
'Some historians have argued that 'caste' in modern India is an 'invention' of colonialism,' it says. 'However, our results indicate that many current distinctions among groups are ancient.'
The downside of enduring endogamy is that genetic flaws which boost the chance of inherited disease get transmitted through the generations.
Screening and mapping India's diversity could enable doctors to help people at risk from their genetic inheritance, says the study.
