A type of genetic drift in which small groups of organisms separate from a larger population and form new small colonies.

• Gene Flow

• Founder Effect

• Natural Selection

• Artificial Selection

The exchange of genes between two populations.

• Genetic Drift

• Founder Effect

• Gene Flow

• Genetic Recombination

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

• Gene library

• Genome

• Gene pool

• Allele pool

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

NGSS.HS-LS4-5

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

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population
