Nоte: this questiоn requires twо written аnswers! Guppies (fish) live in rivers in Trinidаd. Mаle fish in downstream pools are dull colored, which allows them to hide from predators . Fish in upstream pools are brightly colored, which allows them to attract females. A. What mode of natural selection (disruptive, stabilizing, or directional) is operating on guppy coloration in downstream pools, if the more dull fish have higher survival and produce more offspring than fish with intermediate or bright coloration? Explain your answer, using complete sentences. (4 pts.) B. What type of sexual selection (intraspecific or interspecific) is operating on guppy coloration in upstream pools, if females choose to mate with males with brighter colors more often than dull males? Explain your answer, using complete sentences. (4 pts.)
