Color Variation Over Time in Rock Pocket Mouse Populations Activity Educator Materials OVERVIEW This activity serves to reinforce concepts of variation and natural selection presented in the BioInteractive short film The Making of the Fittest: Natural Selection and Adaptation. Color Variation Over Time in Rock Pocket Mouse Populations | This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates.
Color Variation Over Time in Rock Pocket Mouse Populations Life
[Mechanisms of evolution: Grades 9-12] Evolution results from selection acting upon genetic variation within a population. (LS4.B) [Mechanisms of evolution: Grades 9-12] There is variation within a population. (LS3.B) [Mechanisms of evolution: Grades 9-12] Natural selection acts on the variation that exists in a population. (LS4.B, LS4.C) 1. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The illustrations may be out of order. 1. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The illustrations may be out of order. Count the number of light-colored and dark-colored mice present at each location at each. Description This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. Mice living on light-colored sand tend to have light-colored coats, while mice living on patches of dark-colored rock have mostly dark-colored coats.

11 Members Description This animation shows why different fur colors can be advantageous to mice in different environments. Rock pocket mice can have either light-colored or dark-colored fur. As shown in the animation, mice that blend in with their surroundings are harder for owls and other predators to see. COLOR VARIATION OVER TIME IN ROCK POCKET MOUSE POPULATIONS INTRODUCTION A typical rock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips.

Rock pocket mice, Chaeotdipus intermedius, are an ideal system in which to study intraspecific phenotypic divergence because of the extensive color variation observed within this species..

If your class does not cover Hardy-Weinberg equilibrium, you may wish to use another lesson, "Color Variation over Time in Rock Pocket Mouse Populations" (http://www.hhmi.org/biointeractive/color-variation-over-time-rock-pocket-mouse-populations). KEY CONCEPTS AND LEARNING OBJECTIVES 1. The four illustrations (provided by your teacher) represent snapshots of rock pocket mouse populations. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The illustrations may be out of order. Count the number of light-colored and dark-colored mice present at each location at.

Molecular Genetics of Color Mutations in Rock Pocket Mice | In these activities, students transcribe and translate portions of the rock pocket mouse Mc1r gene to further explore the genetic variations responsible for different coat colors as described in the short film Making of the Fittest: Natural Selection and Adaptation. This activity explores physical and genetic evolutionary changes in rock pocket mouse populations, as discussed in the short film The Making of the Fittest: Natural Selection and Adaptation. This film uses the rock pocket mouse as a living example of Darwin's process of natural selection.
