Principles of Natural Selection

All of the alleles of all the individuals in a population is referred to as:

• Genetic equilibrium

• Fitness

• Genetic variation

• A gene pool

What is the process by which individuals that are better suited to their environment survive and reproduce more successfully than those less suited?

• Artificial Selection

• Natural Selection

• Fitness

• Adaptation

Any trait that helps an organism better survive and reproduce in its given environment is called:

• Adversion

• Adaptation

• Variation

• Fitness

• Natural Selection
• Variation
• Homeostasis
• Extinction

When individuals choose traits possessed by the opposite sex it is called…

• Mutation

• Gene Flow

• Genetic Drift

• Sexual Selection

This mechanism of evolution occurs when populations migrate.

• Extinction

• Gene flow

• Genetic drift

• Natural Selection
