b

The genetic makeup of a single chromosome

c

The total collection of genes in a population

d

A group of genes that are always inherited together

2. Genetic drift is most likely to occur in:

a

Large populations

b

Small populations

c

Populations with high gene flow

d

Populations undergoing natural selection

3. The Hardy-Weinberg principle describes a population that is not  .

4.   is the movement of genes into or out of a population.

5. Natural selection always leads to an increase in genetic diversity.

T

True

F

False

6. A bottleneck effect is a type of genetic drift.

T

True

F

False

7. Explain the difference between genetic drift and gene flow.

8. Describe how natural selection can lead to changes in allele frequencies within a population.

9. Examine the diagram of DNA below. Briefly describe its key components and how they relate to heredity.
