Atlantic modal haplotype

In

subclades

of R1b and references to it can be found in some of the older literature. It corresponds most closely with subclade R1b1a2a1a(1) [L11].

The AMH is the most frequently occurring haplotype amongst human males in Atlantic Europe. It is characterized by the following marker alleles:

It reaches the highest frequencies in the

NW Portugal and nearly 90% in Galicia (NW Spain), while the highest value is to be found among Spain and the Basques

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.
