For example, for the mice that lived in the beach area with tan sand, none of the mice had a change in the color of their fur; For simplicity, we will work with two alleles at one gene. Yes, light colored mice are found on light sand beaches;

As Shown In The Animation, Mice That Blend In With Their Surroundings Are Harder For Owls And Other Predators To See.

Each gene has several possible alleles. In rock pocket mice, several genes code for fur color. The term evolution by natural selection does not refer to individuals changing, only to changes in the frequency of adaptive characteristics in the population as a whole.

Fitness (Or Fit), Survival (Or Survive), Selection (Or Selective), And Evolution (Or Evolve).

Traits for curly wings and black body tend to be inherited. Because a mutation for dark fur has not occurred yet). All of the offspring will be white.

In three to five sentences, explain how this trait increased in frequency in the population.

Class Discussion May Extend The Activity, And Procedure.

For example, for the mice that lived in the beach area with tan sand, none of the mice had a change in the color of their fur; Students view a brief video that presents research findings concerning the roles of mutation and natural selection in the evolution of fur color in rock pocket mice. In certain environments, individual mice that have dark fur will survive and have more offspring than mice with tan fur.
