Fig. 4From: Selective sweeps versus introgression - population genetic dynamics of the murine leukemia virus receptor Xpr1 in wild populations of the house mouse (Mus musculus)Phylogenetic tree of P-MLV RBD Env sequences from wild-derived mice. Population of origin and Xpr1 haplotype of the respective individuals are indicated next to the samples. The tree was reconstructed using Bayesian analysis of unphased sequences. Polytomies were collapsedBack to article page
