Figure 2.

Reduced median network relating HVSI sequences of subhaplogroup U6. The central motif (star) differs from rCRS [55,56] at position 16172. Population codes as in Table 2. Numbers along links refer to nucleotide positions minus 16000; suffix indicates a transversion. Individuals marked with * and # additionally present mutations 051 and 048, respectively. Dotted boxes correspond to subgroup U6b1; transversals to U6b; white to U6a; grids to U6a1, and checkered to U6c. Size of boxes is proportional to the number of individuals included. Dotted links represent less probable paths.
