Question 17 of 33

A population of pocket mice has two coat colors: black and brown. There are more black mice on lava 3.0 Points rocks where there are hawk predators. This is an example of:

1. Genetic drift
2. Mutation
3. Natural selection
4. Macroevolution

Feedback: Mice that are the same color as the rock (black) are able to survive predator attacks better because they are more camouflaged. This is an example of natural selection. Read more in Chapter 11.

1. genetic drift
2. mutation
3. migration
4. natural selection

1. Inheritance of acquired characteristics creates a strong evolutionary force.
2. Characteristics are inherited from parent to offspring.
3. Resources are unlimited and arise from the endless supply of energy from the sun.
4. Individuals in a population have the same ability to survive and reproduce.

1. when individual migrate from one population to another
2. when a parent species becomes two species in one location.
3. when populations are geographically separated and diverge.
4. when mutation increases the number of offspring.

1. the change in allele frequency in a population.
2. due to detrimental effects on fitness.
3. the field of study which examine allele frequencies.
4. the change that gives rise to new species.

1. Mutation causes gene flow between populations.
2. Mutation alone is a strong mechanism of evolution.
3. Mutation is the ultimate source of novel variation.
4. Mutation results from bottleneck events.

Feedback: Although there are many processes that can change allele frequencies in a population, only mutation can result in new variation. Read more in Chapter 11.

Question 23 of 33

What are the four evolutionary forces that would disrupt population Hardy-Weinberg equilibrium? 3.0 Points

Question 24 of 33

A classic scientific study showed that crayfish on one side of the isthmus of Panama were more closely 3.0 Points related to other species on the other side of the isthmus than to each other. The most likely explanation for this result is:

1. gene flow
2. vicariance
3. mutation
