For rock pocket mice, which of the following contributes to selective pressure favoring dark-colored fur? Write "yes"or "no" next to each of the four possible responses. 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. The volcanic rock caused the same mutation in each rock pocket mouse population, resulting in dark coloration. A typicalrock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. The same mutation spontaneously arose in the two different populations.Į. The volcanic rock caused the same mutation in each rock pocket mouse population, resulting in dark coloration.Ĭ. The mice in the two populations evolved from the same ancestral population.ī. Which of the following could explain this observation?Ī. Rock Pocket Mouse Microevolution Student Handout by Matthew Butters 4.0 (6) 2.00 Word Document File The Rock Pocket Mice of southwestern United States have demonstrated a very clear and interpretable case for microevolution. 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. 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. Suppose you are studying a recently discovered population of rock pocket mice with dark-colored fur that lives on volcanic rock.
