![]() An interactive version of this film, with pause points and quiz questions. Step-by-step directions for doing the Rock Pocket Mouse activity.- Make a copy of the assignment document.- Follow along with the directions, pausing as you. Let's start by watching a video developed by HHMI Biointeractive about this phenomenon. shows how a rock pocket mouse is a living example of Darwins process of. The sequence you get is identical to that of the same gene in another rock pocket mouse population with dark-colored fur that lives on a different patch of volcanic rock. In orer to investigate this mystery, we're going to investigate this case of pocket mice evolution using computational models. You take a DNA sample from a member of this new population and determine the DNA sequence of a gene known to play a role in fur color. ![]() Researchers noticed that rock pocket mice with a dark fur coat were more common on the dark lava flows, whereas the mice with light colored fur coat were more common on the light-colored sand. Rock Pocket Mouse Video Questions Rock Pocket Mouse Video Questions 1. dark-colored mice that live on black lava rock.light-colored mice that live on sandy soil.Answer: A mutation is a change in the sequence of nucleotides in the DNA of an organism. Today there are now two forms of pocket mice: Answer Key: Natural Selection in the Rock Pocket Mouse Quiz modified from materials related to HHMI BioInteractive teaching materials. Then, a series of volcanic eruptions spewed a river of black lava more than 40 miles long that wove right through the middle of pocket-mouse territory. Lava flows created huge patches of dark rock among the surrounding light-colored sand. This kept the mice hidden from their predators (mainly owls). ![]() Ancestral pocket mice had light-colored fur coats that blended in with the rocks and sandy soil that was prevalent in the region. The colored rock has nothing to do with the actual mutation, mutation are spontaneous, what most likely happened was a mutation occurred at some point and a black rock pocket mouse was born, and because the mouses are the same color as the rock it had better survival chances. The American Southwest is a fantastic place to study rock pocket mice with different fur coat colors.
