Summary Introduction
To determine: The way in which directional selection affects genetic diversity in a population of mice on an island over the long run.
Introduction: Directional selection can be defined as a type of natural selection which favors an extreme phenotype over other phenotypes. It shifts frequency of allele in the direction of extreme phenotype over the time.

REQUIREMENTS FOR NATURAL SELECTION TO OCCUR:
17a. Assuming that both types of pom-poms are present in the population, what do you think
would happen to the pom-pom population if the black forest experienced a prolonged drought
so all the trees died and the habitat became red grassland?
17b. Next, think about an alternative scenario. Suppose that natural selection over many
generations had eliminated all the red pom-poms in the black forest habitat so only black pom-
poms survived. After that, a prolonged drought resulted in this habitat turning into a red
grassland. Would natural selection for pom-pom color occur? Why or why not?
17c. The above scenarios are showing that in order for natural selection to occur
must exist within a trait.
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.
USIBG EVIDENCE FROM THE TEXT, how did natural selection determine the survival of medeival humans during the black death(bubonic plague)?
Use the words: variation, natural selection, favorable traits

Polar bears are highly adapted for life in cold climates around the North Pole. Brown bears, black bears, and pandas are found in warmer environments. Researchers collected complete mitochondrial DNA sequences from several populations of bears and constructed a phylogenetic tree to represent their evolutionary relatedness (Figure 1). A researcher studying adaptation in bears sequenced the nuclear gene encoding a lysosomal trafficking protein (LYST) in polar bears, brown bears, black bears, and panda bears. There are seven inferred amino acid substitutions that are found only in polar bears. Mutations that cause similar substitutions in the…arrow_forward

- Applied Natural Selection: You are studying a population of a newly-discovered species of mammal called grendels. They live here in the woods of CT, and the population has a wide range of thicknesses to their fur coats. Most have a moderately thick coat year-round, including “Bob” and “Dave” and “Smurfette” and “Cindy,” four individuals that you are tracking. But a few such as “Stan” have noticeably thinner coats, and there is even one that you call “Biff” that looks almost naked and has very little body hair at all (a metrosexual grendel, if you will). On the other hand, there are also a few with thicker-than-average coats such as “Penny” and “Silvia,” and one that you have nicknamed “Cousin It” because you can’t even see his eyes through all his lustrous hair.
