Common Traits of Colubridae Snakes. Across the animal kingdom, Hox genes specify positional identities along the headâtoâtail body axis (Kmita and Duboule 2003; Deschamps and van Nes 2005).Nested expression patterns of Hox genes are interpreted by the downstream developmental system, and thus form the basis for morphological patterning in ⦠Size.

Iguana densities were consistently higher in sites located along rivers (2.5 iguanas/group) than in sites along the margin of marshes, probably due to vegetational differences (1.5 iguanas/group).
