This project is a meeting place for users who share the Q-L245 Y-DNA haplogroup, which means they are related along their paternal lines. Users in this group may want to share their family trees with each other to find overlaps and merge duplicate profiles in order to join or expand the World Family Tree and discover new relatives.
Clarification of Y-DNA Haplogroup Q1b Phylogenetic Structure Based on Y-Chromosome Full Sequencing
Gurianov et al., 2015
Abstract
The recent growth of the Y-chromosome full sequencing data sets made it possible to arrange a full-scale update of Q1b haplogroup phylogenetic structure (Q-L275). The article contains a detailed description of Q-Y2200 and Q-YP745 branches as well as a number of other subclades downstream to Q-L275 including their dating as per the method described in the article of Adamov et al. 2015. We also made an effort of inter-discipline review of data from the field of population genetics, archaeology, and comparative linguistics; formalized major problems arisen upon delivering this analysis, and offered a few hypotheses on migration paths of the groups comprising representatives of different Q1b subclades.
