Continuous Variation Quiz

What is continuous variation?

• Sudden change in a trait within a population

• Range of small differences in a trait within a population

• Variation that occurs only in plants

• Variation that is not influenced by genetics

How is continuous variation different from discontinuous variation?

• Continuous variation is caused by genetic factors, while discontinuous variation is caused by environmental factors.

• Continuous variation only occurs in plants, while discontinuous variation only occurs in animals.

• Continuous variation is always visible, while discontinuous variation is always hidden.

• Continuous variation refers to a range of values within a population, while discontinuous variation refers to distinct categories or traits.

Give an example of continuous variation.

• Height

• Shoe size

• Eye color

• Blood type

Explain the concept of continuous variation.

• Continuous variation refers to the variation in a trait that is determined solely by genetic factors.

• Continuous variation refers to the variation in a trait that remains constant throughout an individual's lifetime.

• Continuous variation refers to the variation in a trait that shows a range of small differences, such as height or weight.

• Continuous variation refers to the variation in a trait that shows only two distinct options, such as black or white.

What factors contribute to continuous variation?

• Geographic location, hair color, and eye color

• Genetic variation, environmental influences, and random chance

• Diet, exercise, and sleep patterns

• Age, gender, and height

Compare continuous and discontinuous variation in terms of inheritance.

• Continuous variation is not influenced by environmental factors

• Discontinuous variation is controlled by multiple genes

• Continuous variation is controlled by a single gene

• Continuous variation is controlled by multiple genes and influenced by environmental factors, while discontinuous variation is controlled by a single gene or a small number of genes.

Discuss the role of environment in continuous and discontinuous variation.

• Continuous variation is solely determined by genetics, while discontinuous variation is solely determined by the environment

• The environment has no impact on continuous and discontinuous variation

• The environment only affects continuous variation, not discontinuous variation

• The environment can influence the expression of genes and the development of traits in both continuous and discontinuous variation.

Explain the genetic basis of continuous and discontinuous variation.

• Continuous variation is controlled by monogenic inheritance, while discontinuous variation is polygenic inheritance.

• Genetic basis of continuous variation is controlled by environmental factors, while discontinuous variation is controlled by genetic mutations.

• Continuous variation is controlled by a single gene, while discontinuous variation is controlled by multiple genes.

• Genetic basis of continuous variation is polygenic inheritance, while discontinuous variation is controlled by monogenic inheritance.

How do continuous and discontinuous variation differ in terms of phenotypic expression?

• Continuous variation involves only one value, while discontinuous variation involves a range of values.

• Continuous variation involves a range of values, while discontinuous variation involves distinct categories or groups.

• Continuous variation is only found in plants, while discontinuous variation is only found in animals.

• Continuous variation is not influenced by genetics, while discontinuous variation is influenced by genetics.

Provide an example of a trait that exhibits discontinuous variation.

• Eye color

• Height

• Blood type

• Skin color
