Choose true or false for the following statements.

1. Migration into a population can increase the diversity in the population.

2. A population bottle neck is one type of genetic drift, which decreases genetic variation in a population.

3. Mutation increases genetic variation at a slow rate.

4. Evolution always occurs over a long period of time.

5. Microevolution describes significant changes in allele frequency in a population over many generations.

1,2,3 are true statement.

Explanation:

1.

Migration into a population can increase the diversity in the population and this statement is true. Migration can result in either decrease and increase of diversity.

2. A population bottle neck is one type of genetic drift, which decreases genetic variation in a population. It is again a true statement

3. Mutation increases genetic variation at a slow rate, is also a true statement as mutation causes genetic variation but a very slow rate.

4. False, Evolution always occurs over a long period of time. evolution is a continuous process.

5. Microevolution describes significant changes in allele frequency in a population over many generations is False statement.
