Fig. 1From: Molecular evolutionary and structural analysis of familial exudative vitreoretinopathy associated FZD4 genePhylogenetic tree of Frizzled receptor gene family. Evolutionary history of Frizzled receptor gene family was inferred by neighbor joining method. Complete-deletion option was used to eradicate gaps and missing data. Numbers on branches represent bootstrap values (based on 1000 replications), only the values ≥50% are presented here. Scale bar depicts amino acid substitutions per siteBack to article page
