Sample answer: The dark-colored mouse has a selective advantage in a habitat such as the Pinacate lava flow, which has a dark-colored substrate. Several questions are embedded within the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection. will be. This film uses the rock pocket mouse as a living example of Darwin’s process of natural selection. There are only 11 questions that go along with the video. Allele and Phenotype Frequencies in Rock Pocket Mouse Populations Published August 2012 Revised October 2013 www.BioInteractive.org Page 1 of 4 LESSON TEACHER MATERIALS The Making of the Fittest: Natural Selection and Adaptation ALLELE AND PHENOTYPE FREQUENCIES IN ROCK POCKET MOUSE POPULATIONS OVERVIEW The rock pocket mouse (Chaetodipus intermedius) is one of 19 species of pocket mice in the genus Chaetodipus. However, the dark-colored phenotype became morecommon once there was a selective advantage for it, which indicates that selection is not random. Here is the link to the video: The video is only about 10 minutes. Lava flows created patches of dark rock among the surrounding light-colored sand. came to be so common in some populations of rock pocket mice. ��"�|�-1�rG[����^���Ϋ���i�vVa��G-N Develop a kinematic controller algorithm for the DexTAR parallel robot. "Today there are two forms of pocket mice: light-colored mice that live on sandy soil, and dark-colored mice that live on black lava rock. Naturally occurring mutations to coat-color genes produced mice with dark fur. ... 31. Natural selection chooses the best of the best to survive, so if you can reproduce and survive. Problem 4. Natural Selection and Adaptation Allele and phenotype frequencies in rock pocket mouse populations This activity uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle. ... 4. in New Haven, from a pay phone, and they decide that Bob comes to When the normal Mc1r gene is present, melanocytes, which are melanin-producing skin cells, decrease the production of the dark-colored pigment called eumelanin and increase the production of the light-colored pigment, pheomelanin. Michael Nachman studies the evolutionary processes that led to these marked differences in rock pocket mouse populations.
