II. North & South Bharatiyas Share mtDNA, Which Is Distinct From That of Europeans

Extensive sequencing and statistical analysis of a part of mtDNA which has sustained mutations (the mitochondrial hypervariable region I, HVR I), from reasonable sample sizes, has shown that certain sequences dominant in Europe are uncommon in India, and when found, are almost equally divided amongst the North and South Indians. Conversely, there are sequences common to both the North and South Indians which are uncommon in Europe (4). These data have been used to estimate the time of diversion of the peoples of Europe and Asia in the Pleistocenic era (4), emphasizing that these are phylogenically different peoples (5).

III. North & South Bharatiyas Share Tissue Antigens, Distinct From Those of Europeans

All diploid human cells express a set of proteins on their surfaces, HLA-A, B and C, which can be unique to an individual. They are coded for in the major histocompatibility complex of genes (MHC class I) on chromosome 6. These are the proteins which are recognized as non-self by the immune system in transplant rejection, and are variously called transplant antigens, phynotypic markers, cell-surface markers, etc. All of these proteins in all persons have identical structures and functions, yet can be distinguished from others. Not all 6 class I antigens (3 each from paternal and maternal copies of chromosomes 6) may be unique to an individual; some are identical or similar. MHC class II proteins (DP, DQ, DR) are expressed by some immune system cells only, but may be even more polymorphic.

Analysis of the DNA sequences coding for the different forms of these proteins (alleles) demonstrate that while populations which are closely related, geographically or through known migrations, show similarities in their class I and II MHC antigens, the Asians and the Europeans are distinct, separate but equal, people (6).
