Fig. 4From: Identification and characterization of male reproduction-related genes in pig (Sus scrofa) using transcriptome analysisEvolutionary rates of TSGs in the pig. a Distribution patterns of TSGs and NTSGs in pig based on the value of dS, dN and dN/dS (evolutionary rate), respectively. b dS, dN and dN/dS values between the three gene sets of LCTSGs, MCTSGs and HCTSGs are compared, respectively. All the statistical tests in the panel are based on the one-sided Wilcoxon rank-sum test. * P < 0.05; ** P < 0.01; *** P < 0.001Back to article page
