Summary[edit]

Description
English: Isofrequency map of haplogroup R-S21 (R1b1a1a2a1a1) in West-Europe. Isofrequency lines indicate the artificial limits (of the areas with various nuances of green) between the decreasing S21 values from the peak. The most elevated value of sub-haplogroup R-S21 frequencies (79%) corresponds to The Netherlands. R-S21 frequencies are 77% in Germany, 74% in Denmark, 73% in Belgium, 70% in Austria and 60% in Switzerland. In the Czech Republic R-S21 frequency is 53%. Maximal values of R-S21 for France is Nancy (58%) and for Italy is Torino (26%). Great Britain had an intermediate value. We can see on the map a gradient of decreasing S21 frequencies from the focus towards south-west in France and to south-eastern Italy; there is an other relatively important focus on S21 frequencies in Czechs.
