In many species of lizards, males fight over territories that allow them access to females, and during these interactions males will display sexual signals to competing individuals. Social signals such as coloration, are seemingly favored by sexual selection as they are thought to provide information about individual quality, such as performance capacity. Side-blotched Lizards, Uta stansburiana, exhibit throat color polymorphism (i.e. orange, yellow, and blue badges), which signal alternative life history strategies to conspecifics. Although morphological, behavioral and physiological characteristics have been shown to differ across male morphs, color variation within each morph has not been compared to aspects of …

• Hypothesis: Female guppies do not influence each other’s choice of male guppy
• Predictions: If female guppies do not influence each other’s choice in males, then most females guppies will choose the same male whether alone or in the presence of other females
• Choice is defined as which pane of glass the female interacts more with from 1 to 3 minutes after being introduced to the tank
• 34 Females were used, 17 small and 17 large
