Variation and Polymorphism in the Dorsal Color Pattern of Uta stansburiana stejnegeri

Abstract
The dorsal color pattern of Uta stansburiana stejnegeri can be classified as striped, barbed, cEevron, or patternless. This variation may be an example of genetic polymorphism. The pattern types occur in both sexes and there appears to be only slight ontogenetic change in any individual''s pattern type. Although temperature and sexual maturity in males tend to obscure the color pattern, the basic pattern type is unchanged. Dorsal pattern types were found to vary significantly between the Palo Duro and Kermit populations in Texas. No seasonal variation was detected in the Kermit population.
