Median-joining network of haplotypes shared between Nepal and Bhutan. Note that the 40 shared extended haplotypes described in the text are reduced to 28 when the bilocal Y-STR DYS385 is removed for network construction. Circles represent Y-STR haplotypes (based on DYS19, DYS389I, DYS389II-I, DYS390, DYS391, DYS392, DYS393, DYS438, DYS439), with area proportional to number of instances. Lines represent Y-STR mutational steps.
