Snake reversals and stripes In a study of the survivorship of juvenile garter snakes, a researcher arrived at the model F 4.2 1 0.008R 1 0.102S 1 0.017R2 2 0.034S2 2 0.268RS where F is a measure of the fitness of the snake, R measures the number of reversals of direction during flight from a predator, and S measures the degree of stripedness in the color pattern of the snake. Which is likelier to survive longer, a snake with R 3 and S 1 or one with R 1 and S 3? Source: Adapted from E. Brodie III, Correlational Selection for Color Pattern and Antipredator Behavior in the Garter Snake Thamnophis Ordinoides, Evolution 46 (1992): 128498.
