Life Science Review

Individuals in a population that have a variation which gives them an advantage in their environment are more likely to:

• survive and reproduce.

• die and not reproduce.

• move to a different environment.

• change their characteristics to fit the environment.

Imagine a dry, arid desert island with light colored sand. As scientists, we observe two variations of mice fur colors - light color and dark-color. Which mouse would have the selective advantage to live in this environment.

• The dark color because it is easy for the mice to find prey

• The dark color because it is easy for predators to spot these mice in the surrounding sandy environment

• The light colored mouse because it is easy for this mouse to find prey

• The light colored mouse because it is harder for predators to spot these mice in the surrounding sandy environment
