inherited and environmental variation

What is genetic variation?

• Differences in the population size

• Differences caused by both genetic and environmental factors

• Differences inherited from parents

• Differences caused by the environment

What causes environmental variation?

• Both genetic and environmental factors

• The environment an organism lives in

• Inherited traits from parents

• Surveying the population

Which of the following is an example of genetic and environmental variation?

• Skin color

• Eye color

• Scars

• Height and weight

How is data on variation collected?

• By genetic testing

• Through environmental studies

• By surveying the population

• Through historical records

What is continuous variation?

• How we analyse the results of surveys on variation

• A type of environmental variation

• A type of genetic variation

• A cause of variation

How can genetic variation benefit a population?

• By increasing the population's ability to adapt to changes in the environment

• By making all individuals identical

• By reducing the gene pool

• By eliminating mutations

What role do mutations play in genetic variation?

• They decrease the genetic diversity within a population

• They have no effect on genetic variation

• They are the primary source of new genetic material

• They only occur in response to environmental changes

Which method is commonly used to study genetic variation within a species?

• Observational studies in natural habitats

• Computer simulations of genetic drift

• Genome sequencing

• Surveying opinions on genetic traits

Which factor is not considered a direct cause of genetic variation?

• Mutations

• Sexual reproduction

• Climate change

• Genetic drift

What is the primary benefit of environmental variation for a species?

• It ensures all individuals are identical.

• It decreases the species' adaptability to new environments.

• It increases the species' ability to survive in diverse environments.

• It has no significant impact on the species.
