This chapter examines the genetic structure of the Turks and Caicos iguana, Cyclura carinata carinata. It tests the assumption that overland dispersal does not limit gene flow among populations and attempts to determine if natural selection has played a role in shaping the current genetic structure of this species. It also assesses the relationship between geographic distance and genetic differentiation and how this relationship may have been affected by vicariance and dispersal. Finally, it considers the implications of the current genetic structure of Cyclura carinata carinata for future conservation initiatives.

Keywords: Turks and Caicos iguana; Cyclura carinata carinata; natural selection; geographic distance; genetic differentiation
