... shows that many of the open reading frames in mammalian Hox genes are more conserved than expected on the basis of their protein sequence. The presence of highly conserved DNA elements is thus ... body axes, Hox genes are also necessary for organogenesis. Mammals have 39 Hox genes, which are organized in four genomic clusters (HoxA, B, C and D) with 13 paralogous groups...
