Chapter 20.10, Problem 2LO
Summary Introduction
To determine: Theeffect of pleiotropy and epistasis on evolutionary response to selective pressure.
Introduction: Selection pressure does lead to evolution, but it is not the requirement for evolution to occur. The members that are fit to survive in the changing condition will evolve into a more efficient and improved species.

- For your summer research project, you decide to repeat Lillian Tuttle’s (2017) experiment testing the effect of lionfish on other fish that are cleaners and clients. You do this new experiment at a new location (Bonaire), but use basically the same experimental approach and BACI design as Tuttle. a) You do not separate resident and transient clients (as Tuttle did), and below is a graph of your results showing the effect of the treatment on the total density of client fish in the community. Please explain your result. Imagine that you are planning to publish your experiment and that your answer to this question will be part of the “Results” section of your paper. Please do not worry about hypothetical statistical tests; just assume that the obvious patterns displayed in the graph can be interpreted at face value.arrow_forwardWhich of the following statements best applies to the term adaptation? * A.
