Imagine that you conduct a phylogenetic analysis of sticklebacks and their relatives
You find that even though stickleback males are the only ones that show red coloration as a derived trait, female preference for red color is indeed found throughout the stickleback relatives. In sticklebacks, red color intensity in males is positively correlated with health, which led researchers to invoke the good genes model for the evolution of red coloration. Do your results change this conclusion in favor of sensory bias as an explanation? a. No, we can exclude sensory bias, as red coloration is still an honest indica-tor of male health. b. Yes, according to the new results the sensory bias model is the most parsi-monious explanation and good genes can be excluded. c. Not necessarily, one model does not exclude the other. d. If females have healthier offspring when they mate with red males, sensory bias can be excluded. e. A and D.
