Indian-Asian relationship: mtDNA reveals more.

Recent studies on human mtDNA have identified continent-specific restriction enzyme sites and resultant haplo-groups among populations from different regions of the world. Such studies have helped in elaborating the models for human migrations. We have studied Indian mtDNAs to identify the recognized world ethnic elements present in it. The results presented here are based on the study of DdeI 10394 site along with the associated Asian-specific AluI 10397 site in the mtDNA sequences of the Indian samples. On examining all the related haplo-groups, this study suggests that the apparent affinities of Indians and East Asians (comprising Chinese, Japanese, Southeast Asians etc.) could be due to a proto-Asiatic element present in Indians.
