Maximum likelihood phylogram of V1R genes and pseudogenes in mouse Chromosome 6 and rat Chromosome 4 clusters. Rat V1R gene clades are shaded gray. To construct this tree, 675 bp of nucleotide sequence was manually aligned such that gaps were minimized. The tree is rooted by the ps1/R1 orthologs based on an outgroup analysis using more distant V1Rs (data not shown). The root branches for the three major subfamily clades (B, A7, and A) are indicated. Bootstrap values (1000 parsimony replicas) are shown on branches if >50%.
