Modern geographical spread of the farmers related N1a1 subclades:. a & b depict the eastern and central European origin of the farmer DEB3, FLO1 and HAL2 types affiliated N1a1a1 and N1a1a2 lineages distribution; c & d representing the farmer UWS5 and DEB1 & ECS1 related N1a1a3 and N1a1b subclades haplotypes distribution in the Near East and southern Europe region. Circle areas are proportional to haplotype frequencies.
