Figure 2. Illustrative representation of the presence of Hh and syntenic related genes in vertebrates according to Genomicus 64.01 [37] and the GenBank [42] and Ensembl [38] databases.

Information for all vertebrate and invertebrate species listed on Genomicus 64.01 [37]. A dotted line between two genes is equivalent to a gap in the alignment, i.e. the two genes are neighbors in this species but not in the reference species, where their orthologs are separated by one or more genes. On the other hand, a large white space indicates that the genes are found on the subject genome but are located on different chromosomes/scaffolds. A question mark (?) indicates that the syntenic relationship is not known. Genes outlined by a black line where found using Genomicus 64.01 [38] and genes outlined by a grey line were found by blast searches over the GenBank [42] and Ensembl [38] databases. The absence of a gene represents that that gene is not annotated on Genomicus 64.01 and was not found by blast searches.
