Selection Quiz

What is the foundation of evolution?

• Natural selection

• Variation

• Genetic drift

• Environmental factors

What role do differences in structure, behavior, and physiology play in evolution?

• They hinder natural selection

• They are irrelevant to evolution

• They play a crucial role in natural selection and survival

• They only affect artificial selection

Which processes contribute to certain traits becoming more prevalent in populations over time?

• Mutation and recombination

• Natural and artificial selection

• Migration and isolation

• Extinction and speciation

What factors contribute to how species evolve and adapt to their surroundings?

• Only genetic drift

• Only environmental factors

• Environmental factors, genetic drift, and founder effects

• Only founder effects

What is the primary reason natural selection occurs in populations?

• Populations have limited resources.

• Individuals are best adapted to survive.

• Populations have the capacity to produce many offspring.

• Environmental factors are stabilizing.

What principle is used to calculate allele and genotype frequencies in populations?

• Mendelian inheritance

• Hardy-Weinberg principle

• Genetic drift

• Natural selection

How do favorable adaptations affect evolutionary change?

• They provide no advantage in specific environments.

• They allow individuals to thrive and are the cornerstone of evolutionary change.

• They hinder the process of natural selection.

• They ensure that all individuals are identical.

How does natural selection affect allele frequencies within a population?

• Increases the frequency of alleles conferring disadvantages

• Decreases the frequency of alleles conferring advantages

• Increases the frequency of alleles conferring advantages

• Has no effect on allele frequencies

What is stabilizing selection?

• A process that favors extreme traits in a population

• A process that reduces variation by favoring average traits

• A process that increases variation by favoring rare traits

• A process that occurs when the environment changes rapidly

Which of the following is a consequence of the Founder Effect?

• Increased gene flow from the original population.

• Genetic drift leading to different evolution from the original population.

• Enhanced environmental adaptation.

• Stabilized genetic variation.
