A haplogroup is a genetic population group of people who share a common ancestor on the patrilineal or matrilineal line. Haplogroups are assigned letters of the alphabet, and refinements consist of additional number and letter combinations.ecause a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from the haplotype. A SNP test is required to confirm the haplogroup prediction. Not all the testing companies offer SNP testing, and consequently their customers' haplogroup predictions are sometimes inaccurate.
In human genetics, Haplogroup R1b is the most frequently occurring Y-chromosome haplogroup in Western Europe, parts of central Eurasia (for example Bashkortostan), and in parts of sub-Saharan Central Africa (for example around Chad and Cameroon).ook-up mtDNA Haplogroup H at Wiki: In human mitochondrial genetics, Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup that likely originated in Southwest Asia 20,000-25,000 YBP.
