Variation Quiz

What is continuous variation?

• The average value of a trait within a population

• The maximum value of a trait within a population

• Range of values that a trait can take on within a population

• The minimum value of a trait within a population

Give an example of continuous variation.

• Height

• Eye color

• Weight

• Blood type

What is discontinuous variation?

• Discontinuous variation refers to traits that have overlapping groups.

• Discontinuous variation refers to traits that have intermediate forms.

• Discontinuous variation refers to traits that have distinct categories or groups with no intermediate forms.

• Discontinuous variation refers to traits that have continuous categories.

Give an example of discontinuous variation.

• Presence or absence of a certain trait

• Eye color

• Height of a person

• Blood type

What are the factors that contribute to continuous variation?

• Multiple genes and no environmental factors

• Single gene and environmental factors

• Single gene and no environmental factors

• Multiple genes and environmental factors

What are the factors that contribute to discontinuous variation?

• Genes

• Heredity

• Mutation

• Environment

What is the main difference between continuous and discontinuous variation?

• Continuous variation refers to traits that are inherited, while discontinuous variation refers to traits that are acquired.

• Continuous variation refers to traits that are influenced by the environment, while discontinuous variation refers to traits that are not influenced by the environment.

• Continuous variation refers to traits that are controlled by multiple genes, while discontinuous variation refers to traits that are controlled by a single gene.

• The main difference between continuous and discontinuous variation is that continuous variation refers to traits that can take on a range of values within a population, while discontinuous variation refers to traits that can only take on specific, distinct values.

Why is it important to study continuous and discontinuous variation?

• To determine the average variation within a population or species.

• To identify the specific genes responsible for variation.

• To predict future evolutionary changes based on variation.

• To understand the range and types of variation within a population or species.
