In
human genetics, the Atlantic Modal Haplotype (AMH) is a
Y-chromosome haplotype of
Y-STR microsatellite variations, associated with the
R1b haplogroup. The AMH is the most frequently occurring haplotype amongst human males in
Atlantic Europe. It is characterised by the following marker
alleles:DYS388 12DYS390 24DYS391 11DYS392 13DYS393 13DYS394 14 (also known as DYS19)One mutation in either direction, would be AMH 1.15+. The AMH 1.15 set of haplotypes is also referred to as the Atlantic Modal Cluster or AMC. Often 1.15+ would be a haplogroup 1 (H1), but not always.
