From: Dynamic evolution of the GnRH receptor gene family in vertebrates
Comparison of deduced amino acid sequences for the three amphibian GnRH receptor genes, aligned using MUSCLE [[32]] . Each of the three genes identified in frogs has a clear ortholog in axolotls. Amino acids that are highly conserved (>80% sequence identity) are indicated with the darkest shading; lighter shading indicates 60-80% identity; the lightest shading indicates 40-60% identity; and a white background indicates low conservation (<40% identity). Latin names of species and GenBank accession numbers for sequences are provided in Additional file 1: Table S1.
