the human genome mapping being complete, some sort of virus manufactured that only works on certain markers present in specific ethnicity groups. for example, a cursory chatgpt query reveals: however, some genetic markers are more prevalent in certain populations due to evolutionary, historical, and environmental factors, as well as genetic isolation. here's a summary of markers often studied in indian populations: 1. y-chromosome haplogroups (paternal lineage):  haplogroup h (h1a, h2): found predominantly in the indian subcontinent, particularly among dravidian-speaking groups. it is less common outside south asia.  haplogroup r2a: common in south asia and linked to ancient migrations within the region.  haplogroup l (l1): frequently found in south asia, especially among certain caste groups. 2. mitochondrial dna haplogroups (maternal lineage):  m haplogroup: subclades such as m2 and m6 are highly prevalent in indian populations and represent ancient maternal lineages unique to the region.  u haplogroup (u2): u2 sublineages, particularly u2a, u2b, and u2c, are more common in indian populations than elsewhere.
