Suppose that a population of caterpillars is polymorphic for color: the allele for brown (G) is dominant to that for green color (g). You hypothesize that brown beetles have a fitness advantage over green beetles because the species prefers to rest on the brown twigs, making the brown form difficult for predators to detect. You capture, mark and release 112 brown and 66 green caterpillars, the recapture them later to measure survival. You recapture 56 brown and 22 green caterpillars. On the basis of these data, determine the fitness (W) and selection coefficient (s) for each genotype. Do these data appear to support your hypothesis about the relative fitness of each phenotype?

Someone seems to be too lazy to do his homework himself.

Well done Alan...

But you dont need to rack your brain with them. There are more important things to do, problems to solve in the world.

Good luck...
