Neighbor Joining phylogeny of Xiphophorus and Poecilia LWS opsin genes . NJ tree was reconstructed using the GTR+I+G model of evolution. Within the tree, values from 1000 bootstrap reiterations are labelled at the nodes. Nodes with values less than 50% were collapsed. LWS sequences from the five teleost species used for gene synteny comparisons in this study were also included. The Xenopus tropicalis LWS gene sequence was used as the outgroup. Species and gene names are labelled at each of the tips in the phylogeny.
