Question: One Answer Are Correct.) Natural Selection and Adaptation _____ 7. Didelphis virginiana. While rewatching the video from Activity 1 on the rock pocket mouse, consider what is happening from a different perspective - traits and the survival rate of mice. The dark mice came about through the process of evolution. 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. Draw the differential manometer which is carrying fluids of different specific gravities. 6. ... 4.

The rock pocket mouse (Chaetodipus intermedius) is one of 19 species of pocket mice in the genus Chaetodipus. A typical rock pocket mouse is 172 millimeters long from nose to rump, which is shorter than an average pencil. Normal pocket mice in Arizona have brown fur, but some live on dark volcanic rock, and have an adaptation for dark fur. Natural selection allowed the dark-furred mouse to reproduce and survive because of the genetic variants in this population and thus helps us comprehend the idea natural selection can contribute to the predominance of certain traits while eliminating other traits that are not suitable to the environment in different populations. 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.
