From: Evolution of coding and non-coding genes in HOX clusters of a marsupial
Organization of HOX gene clusters, long non-coding RNAs and microRNAs in human and tammar. The tammar has 39 HOX genes located in 4 separate clusters—HOX-A, -B, -C and -D—which show highly conserved organization. Three conserved long non-coding RNAs (HOXA11AS, HOTAIRM1 and HOTAIR) were also present. Orthologous genes are the same color and introns filled with the grey color. The homologous long non-coding RNAs are the same color in the star while homologous microRNAs are also the same color. Question mark (?) represents the predicted microRNAs by sequence alignment.
