NGSS.HS-LS4-4

NGSS.HS-LS4-3

Genetic drift resulting from the reduction of a population, typically by a natural disaster, such that the surviving population is no longer genetically representative of the original population.

• Bottleneck effect
• Natural selection
• Genetic recombination
• Founder's effect

A measure of fitness that compares reproductive success between groups of individual within a population.

• Differential reproductive success
• Niche
• Migration
• Gene flow

NGSS.HS-LS4-4

NGSS.HS-LS2-8

Genetic drift in which a small group of individuals breaks away from the original population and establishes a new colony which can be very different from the original population.

• Founder's effect
• Variation
• Migration
• Genetic drift

Due to the migration or movement of gametes, genes are transferred from one population to another.

• Gene flow
• Adaptation
• Variation
• Genetic recombination

All the genes in a given population

• Gene pool
• Bottleneck effect
• Niche
• Migration

The change in allele frequency due to random chance; usually has a greater effect on a smaller population.

• Genetic drift
• Differential reproductive success
• Gene Flow
• Mutation

New genetic combinations in gametes created during crossing over in meiosis, resulting in genetic variation.

• Genetic recombination
• Fitness
• Selection pressure
• Natural selection

NGSS.HS-LS3-2

The movement of organisms between populations which brings new alleles into or out of a population and changes the gene pool.

• Migration
• Founder's effect
• Variation
• Niche
