Fig. 1From: Convergent reduction of V1R genes in subterranean rodentsRepertoire sizes of intact V1Rs in 24 rodents. The phylogenetic relationship of 24 rodents was obtained from multiple sources (Additional file 1: Table S2). Based on their lifestyles, these rodents are divided into two groups: superterranean rodents (red) and subterranean rodents (blue)Back to article page
