Phylogenetic Structure of Q-M378 Subclade Based On Full Y-Chromosome Sequencing
Q-M378 subclade, which is downstream of Q-L275 haplogroup, is marked by a wide area of its distribution and a minor share of presence in modern populations of Eurasia. Phylogenetic structure of the subclade, known so far, did not allow for matching SNP Y-chromosomes to specific populations and to reconstruct possible directions of their migrations in retrospect.
The conducted research enabled us to form a consistent phylogenetic structure of Q-M378 subclade, validated by analysis of SNP and STR-markers, based on the data of full Y-chromosome sequencing using next generation sequencers. As part of the research, new phylogenetic levels of Q-Y2250 (downstream of Q-M378 and including Q-L301), Q-Y2220 (downstream of Q-L245), Q-
Y2200 (downstream of Q-Y2220) were defined.
SNPs, which, in the future, may possibly mark certain European and Asian subclusters of Q-Y2220 (including the Armenian subcluster), as well as separate branches of the Jewish cluster Q-Y2200, were defined as well.
The research also confirmed connection of Q-M378 subclade distribution with migration of Indo-European language carriers from Central Asia via Afghanistan and Iran to the West.
