Mechanisms of Evolution Quiz

This term refers to the total genetic information found in a population; the complete collection of all the alleles found in a population

This is one of the mechanisms of evolution; it occurs when individuals move into or out of a population, either by physically arriving or leaving, or by being born or dying

• Gene flow / genetic drift

• Founder effect

• Natural selection

• Microevolution

This is one of the mechanisms of evolution; it is a continuous process in which organisms with traits that make them better-adapted to their environment are more likely to survive and reproduce than organisms without such adaptations

• Directional selection

• Microevolution

• Gene flow / genetic drift

• Natural selection

This occurs when a large population is drastically reduced by an event such as a natural disaster; the population's new gene pool only contains alleles from the survivors

• Founder effect

• Bottleneck effect

• Meteor effect

• Natural selection

This is the process that ultimately creates new variations and changes in DNA; leads to the creation of new alleles

• Mutation

• Microevolution

• Natural selection

• Gene flow / genetic drift

Today, the Afrikaner population has an unusually high frequency of the gene that causes Huntington's Disease, because the Dutch colonists happened to carry that gene with unusually high frequency.
