Variations Quiz

Which of the following is a source of variation?

• Genetic differences

• Environmental factors

• Mutations

• All of the above

Which of the following best describes the difference between continuous and discontinuous variation?

• Continuous variation shows a range of phenotypes, while discontinuous variation shows distinct categories.

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

• Continuous variation is not influenced by the environment, while discontinuous variation is.

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

Which of the following is a method to investigate the effect of environmental factors on phenotypic variation in plants?

• Conducting a controlled experiment with varying environmental conditions

• Observing plants in their natural habitat without intervention

• Studying genetic sequences of plants

• Measuring the height of plants in a single environment

Evaluate the statement: "Genetic variation is the primary driver of evolution."

• True

• False

Consider a scenario where a population experiences a sudden change in climate. What are the potential effects on genetic variation?

• Increase in genetic variation due to new mutations

• Decrease in genetic variation due to selective pressures

• No change in genetic variation

• Complete loss of genetic variation

Differentiate between continuous and discontinuous variations.

• Continuous variations show a range of phenotypes, while discontinuous variations show distinct categories.

• Continuous variations are influenced by a single gene, while discontinuous variations are influenced by multiple genes.

• Continuous variations are not influenced by the environment, while discontinuous variations are.

• Continuous variations are not heritable, while discontinuous variations are.
