Haplogroup A

Wednesday 28 September 2005


- Native Americans
- Chukchi and Siberian Eskimos


- The sequence-divergence estimates for Haplogroup A, Haplogroup C, and Haplogroup D of Siberian and Native American populations indicate that the earliest inhabitants of Beringia possessed a limited number of founding mtDNA haplotypes and that the first humans expanded into the New World approximately 34,000 years before present (YBP). (9792876)

- A 16111C—>T transition appears to delineate an "American" enclave of Haplogroup A mtDNAs in northeastern Siberia, whereas the 16192C—>T transition demarcates a "northern Pacific Rim" cluster within Haplogroup A. (9792876)
