Abstract

We investigated quantitative variations and inheritance of the dorsal color pattern of Uta stansburiana stejnegeri exclusive of the strongly sexually dichromatic spotting pattern. The color pattern was quantified by measuring both the variation in stripe width and the proportion of the body that was striped. Each measurement technique resulted in a single value representing the color pattern of each individual. There was no strong quantitative relationship between variations of the color pattern either of mothers and sons or mothers and daughters. Therefore, heritability, if present, could not be detected. However, the color patterns of mothers and daughters tended to be similar, but the color patterns of mothers and sons differed significantly. This suggests a genetic basis for previously documented adult difference in aspects of the dorsal color pattern not obviously related to social displays.
