Tracing the Indian genome

E878013D5436C22DCFF9190E7BA8B1F9A new genomic reconstruction of mainland India’s population shows the Indian genome to be a blend of at least four dominant ancestries and not just two as reported by earlier studies.
Scientists at the National Institute of Biomedical Genomics (NIBG), Kalyani, West Bengal state, who published their findings in Proceedings of the National Academy of Sciences in January, found four ancestries — Ancestral North Indian, Ancestral South Indian, Ancestral Austro-Asian and Ancestral Tibeto-Burman — present in populations across India.
“The diversity was such that geographical distance did not mirror genetic distance in the case of Indians,” Analabha Basu, assistant professor at NIBG and lead author of the study, tells SciDev.Net.
