Abstract
Studies of chromosomal variation were undertaken in Anolis grahami. Multiple fission events and extensive variation involving heterochromatic sequences were observed. Distribution of the chromosomal variants did not coincide with subspecies borders. Chromosome numbers ranging from 30 to 37 were observed in both morphological subspecies; different rearrangements were involved in each. C-banding studies revealed cryptic variation in a large macrochromosome of some populations of A. g. grahami, and the presence of an additional heterochromatic arm in A. g. aquarum. Patterns of distribution of various forms, including widespread polymorphism, suggest significant dispersal of Anolis grahami, and little selection against chromosomal heterozygotes.
