Fig. 5From: Genomic sequence analyses of classical and non-classical lamprey progesterone receptor genes and the inference of homologous gene evolution in metazoansAnalysis of conserved synteny blocks harbouring mPRε (a) and neudesin (b) among five chordates. Solid circle represents the end of scaffold. Orange and blue blocks indicate the PR and its adjacent conserved genes, respectively.
