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.
H1 â H1 is the most common branch of haplogroup H. It represents 30% of people in haplogroup H, and 46% of the maternal lineages in Iberia. 13-14% of all Europeans belong to this branch, and H1 is about 13,000 years old.H1a â H1a is a branch of H1.aplogroup (Hg) H alone constitutes about one half of the European mtDNA pool and, along with other aforementioned lineages, is widespread also in western Asia (Macaulay et al. 1999; Richards et al. 2000; Tambets et al.
