Chapter 19.4, Problem 1CC

Let’s suppose the climate on an island abruptly changed such that the average temperature was 10°C higher. The climate change is permanent. How would directional selection affect the genetic diversity in a population of mice on the island (1) over the short run and (2) over the long run?

In the Grants’ study of the medium ground finch, do you think the pattern of natural selection was directional, stabilizing, disruptive, or balancing? Explain your answer. If the environment remained dry indefinitely (for many years), what do you think would be the long-term outcome?
Based on (MS-LS4-4) standard(grade8) - Mathematical Representations of Natural Selection: Most scientists think that a small group of finches colonized the Galápagos Islands thousands of years ago. They would have been the only seed-eating birds on the islands. Suppose one island was very dry and another had plentiful rainfall.    Q)How would the finch populations on these islands change over time? Reference to the evidence from data (pictures of Data Set C - Galapagos Islands Finch - 25cm Average Rainfall and Data Set C - Galapagos Islands Finches - Rainfall Effect are attached) and reasoning to support your claim to support your claim. Kindly use also examples outside of the prompt and vocabulary for explanation.
The evolution of a qualitative trait in reponse to natural selection is described by the following equation,       R=h2 S a) What is h2 and what does it measure? b) Describe a study that would allow you to estimate h2 for a real population
