Fig. 4From: Frequent birth-and-death events throughout perforin-1 evolutionBirth-and-death in fish perforin-1 evolution. Left, phylogenetic relationship between selected teleost species. Middle, Birth-and death events according to a model of maximum parsimony. Duplications are highlighted in red, and predicted gene losses are depicted in grey. Branches showing conserved loci are highlighted in brown. Right, selected PRF1 loci corresponding to branches in the birth-and-death treeBack to article page
