Question
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.

A. Set up a number of experiments to ensure that the explanatory variable is truly the cause of the response variable. B. Use a bar graph to compare the means of the two variables. If they are close together, then they are related. C. Graph it on a scatterplot and find the R-squared value. If the R-squared value is close to 1.0, it proves the correlation. D. Graph it on a histogram and look for the mean of the data.arrow_forward
- You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.

Which of the following examples is consistent with this statement? Some lizards in complex tropical forests prefer to hang out on tree trunks and branches, rather than the ground substrate, which has resulted in selection for shorter relative limb length and toe pads that can cling to bark. Ground-burrowing mammals experience greater exposure to dust and increased selection on their respiratory system to filter these particulates. Specialist parasitoids only target a handful of different host/prey types, resulting in a predictable resource and less selection on the ability to learn new resources All of the above Imagine that scientists have just discovered a weird new marine tunicate at extreme depths of the ocean. They have a novel kind of neurotransmitter – maritonin – that binds to the “maritonin” receptor, which is permeable to negatively charged iodine ions…arrow_forward
