Fig. 4From: Viviparity and habitat restrictions may influence the evolution of male reproductive genes in tsetse fly (Glossina) speciesConsensus evolutionary analysis of orthologous genes in the six Glossina species. Upper and lower are the trees derived from analyses of nonsynonymous (dN) and synonymous (dS) substitutions, respectively. MAGGs, TSTGs, and “all genes” are represented (from left to right). The dN/dS for each species is given in parenthesesBack to article page
