Haplogroup Q-L275 or Haplogroup Q2 (formerly Haplogroup Q1b) is a

human Y-chromosome DNA haplogroup In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of sh ...

Q-L275 has descendants across Europe, Central Asia, and South Asia.

Q-L275 has not been identified in pre-Columbian groups in the Americas. Potential sources in indigenous populations are European

The problematic phylogeny sampling of early studies has been demonstrated by subsequent studies that have found the Q-M378 descendant branch in South Asia.

West Asia

According to Behar et al. 5% of Ashkenazi males belong to haplogroup Q. This has subsequently been found to be entirely Q-L275's Q-M378 subclade and is further restricted to the Q-L245 branch.

Subclade Distribution

Q-L245 This branch was discovered by citizen scientists. It is a descendant branch of the Q-M378 lineage and is the most common branch in West Asian groups such as Iranians and Jewish populations. Q-L272.1 This branch was discovered by citizen scientists. It has only been identified in one Sicilian sample. Q-L301 This branch was discovered by citizen scientists. They have identified it in two unrelated Iranian samples. Q-L315 This branch was discovered by citizen scientists. It has only been identified in one Ashkenazi Jewish sample. Thus, it is presumed to have arisen after the Q-L245 branch to which it belongs became part of the pre-Diaspora Jewish population. Q-L327 This branch was discovered by citizen scientists. It has only been identified in one Azorean sample. Q-L619.2 This branch was discovered by citizen scientists. They have identified it in two unrelated Armenian samples. Q-P306 This branch was discovered by the
