They recorded substrate color and coat-color frequencies for each location. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. In this activity, students explore fur color variation in rock pocket mice populations by analyzing and comparing short sequences of DNA to identify mutations. Each illustration shows the color variation. Allele and Phenotype Frequencies in Rock Pocket Mouse Populations of 4 LESSON TEACHER MATERIALS The Making of the Fittest: Natural Selection and Adaptation p2 0.04, or 4 Explanation: q2q 0.8 because p + q 1, p 0.2 and p2 (0.2)(0.2) 0.04 PART 2: APPLYING HARDY-WEINBERG TO POCKET MOUSE FIELD DATA 1. PART 2: APPLYING HARDY-WEINBERG TO ROCK POCKET MOUSE FIELD DATA. You can find populations of rock pocket mice all over the Sonoran Desert in. Students then watch the HHMI Video on pocket mice and answer discussion questions. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Youll get a detailed solution from a subject matter expert that helps you. Students also graph the color differences at each location to show how the dark variation increased over time in response to an environmental change. (Cards can be printed and laminated for multiple uses.) Students collect data on the number of mice phenotypes in each location and develop a hypothesis about the order of the cards.

You can find populations of rock pocket mice all over the Sonoran Desert in the southwestern United States. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips. Remember that 'fitness' is defined by an organisms ability to survive and produce. Explain why a rock pocket mouses color influences its overall fitness. To end the lesson and allow students to synthesize all they have learned, students answer the following analysis questions (on data sheet): 1.

A typical rock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. PDF Rock Pocket Mouse Worksheet Answer Key. It has been simplified from the original activity so that it is suitable for beginner biology students. This worksheet was modified from the HHMI Activity on color variation in the rock pocket mouse.
