Figure 3

Histograms showing the distributions of F _ij , the frequency of each variant j within each individual sample i. Data were grouped as a function of m, the maximal number of variants for the gene within a sample: (A) for m = 2, (B) for m = 4 and (C) for m = 8. Histograms on the right display the distributions for values below ten percent: (D) for m = 2, (E) for m = 4 and (F) for m = 8.
