Sequence conservation in Hoxa clusters. VISTA plot [31] comparing the Little Skate Hoxa cluster (base sequence) with the orthologous regions in other vertebrates (from top to bottom: Heterodontus francisci, Homo sapiens, Xenopus tropicalis, Latimeria menadoensis and Polypterus senegalus). Shading indicates regions of 100 bp or more that are ≥ 70% identical in either exons (blue) or intergenic/intronic regions (pink).
