The dark coloring of the Kenzin, Armendaris and Carrizozo dark mouse populations is not caused by mutations in the Mc ir gene, but a change in a different gene that controls coat color The Pinicate dark mouse population has four mutations in the Mclr gene, all of which change the amino acids at those positions compared to the same amino acid positions in the Pinicate light mouse The Kenzin, Amendaris and Carnizozo dark mouse populations have the same amino acids in the indicated positions as does the Pinicate light mouse population The mutations in MCR are all located next to each other in the amino acid sequence of the protein. 1.34 QUESTION 12 Refer to the amino acid chart that you completed for step 3 of the worksheet 'Natural Selection and Evolution of Rock Pocket Mouse Populations to answer this question Which of the following statements is FALSE? The Pinicate light mouse population is the wild-type' phenotype. The mice are light-colored There is a decrease in the production of dark-colored pigment eumelanin The protein MC1R is present in the melanocytes. Inheritance The variation in the trait of interest is at least partially inherited (passed from parents to offspring). Color Variation over Time in Rock Pocket Mouse. Allele and Phenotype Frequencies in Rock Pocket Mouse Populations. Black mice may be found in a population of tan mice with a frequency of about 1 for every 100,000 births.

There are black rock pocket mice and tan rock pocket mice, and they belong tothe same species. finance true minutes else mark rock third gifts europe reading topics bad. The student materials are also found in the. Not all downloadable documents for the resource may be available in this format. The teacher materials hold many teaching tips and the answer keys. The “Resource Google Folder” link directs to a Google Drive folder of resource documents in the Google Docs format. The images are arranged from oldest to youngest in time. Each image represents a snapshot in time of two locations: A and B. By comparing DNA sequences, students identify the locations and types of mutations responsible for the coat-color change described in the film. Examine the population of rock pocket mice populations over time.

They then compare amino acid sequences to identify variations associated with different coat colors. Students will transcribe and translate portions of the wild-type and mutant rock pocket mouse Mc1r gene. An evolutionary biologist demonstrates how to break open pieces of rock without damaging delicate more.

They then use a genetic code chart, to determine the amino acids encoded by a sequence of the Mc1r gene in different mouse populations. The activity begins with students reading a magazine article and watching the film. Simulating Evolution of a Rock Pocket Mouse Population. At the beginning of the lesson, students place four illustrations showing different numbers of light and dark colored rock pocket mice at two locations. You will apply the Hardy-Weinberg equation to real data collected on rock pocket mouse populations by Michael Nachman and his colleagues, who looked at the. Students analyze genetic sequence data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse. Unit Plan: Natural Selection & EvolutionLesson: 5 Time: One or two class periods Setting. This activity supports concepts covered in the film Natural Selection and Adaptation.
