Fig. 2From: Selective sweeps versus introgression - population genetic dynamics of the murine leukemia virus receptor Xpr1 in wild populations of the house mouse (Mus musculus)Map of population locations and haplotype frequencies. Haplotype assignments correspond to the designations in Fig. 1. Frequencies are depicted as pie charts. Green stars denote significantly elevated values of Tajima’s D in the respective populations.
