Distribution of R1a (purple) and R1b (red). See also this map for distribution in Europe. In human genetics, Haplogroup R1b (M343) (previously called Hg1 and Eu18) is the most frequent Y-chromosome haplogroup in Europe.Its frequency is highest in Western Europe, especially in Atlantic Europe (and due to European emigration, in North America, South America, and Australia).istribution of R1a (purple) and R1b (red).

What is immediately apparent to genetic genealogists is that the map of red hair correlates with the frequency of haplogroup R1b in northern and western Europe. It doesn't really correlate with the percentage of R1b in southern Europe, for the simple reason that red hair is more visible among people carrying various other genes involved in light skin and hair pigmentation.
