Hemoglobin and transferrin electrophoresis and relationships of island populations of Anolis lizards.

Electrophoretic differences in hemoglobins and transferrins serve to differentiate Anolis of the same species populating the Lesser Antilles. When based on protein analyses, identifications of individuals may be less equivocal than identification based on descriptions of skin color and markings. Protein differences among island populations appear to be associated with long periods of geographic isolation. Such evidence often confirms estimates of relationship derived from more traditional criteria and in some cases provides a basis for formulating new taxonomic conclusions.
