Main migratory events from Beringia/Asia towards North America and back migrations according to the Y-chromosome variation. Schematic representation of the spread of the Q-L54 sub-lineages Q-L804 and Q-L330 in Eurasia and of Q-Z780, Q-M848 and Q-Y4276 from Beringia to North America (A.1) and back migration to Asia of Q-B34 (A.2). For Q-Y4276, we propose two possible entry routes (dashed lines) into North America. B Schematic representation of the spread of the Q-F1096 sub-lineages Q-L713 and Q-M120 in Eurasia and of Q-L713, Q-preM120 and Q-B143 in Arctic North America. While Q-pre-M120 and Q-L713 mark migrations towards North America apparently unsuccessful in terms of Y chromosomes, Q-B143 reached Greenland. The presence of recent Q-B143 Y-chromosomes in the Koryaks of Siberia can be explained by a back migration. The two insets illustrate the phylogenetic relationships of the Q sub-lineages (in different colours). Stars highlighted by a grey shading refer to ancient samples
