Gene Pool

What is gene flow?

• The addition or removal of alleles in a population due to individuals entering or leaving one population for another

• A change in allele frequencies when a new population arises from only a few individuals

• A reduction in population caused by natural disasters, disease, hunting, etc.

• A change in the gene pool due to chance

Select all answers below that describe the founder effect.

• Changes allele frequencies

• Occurs when a new population arises from only a few individuals

• Can result in a loss of genetic diversity

• Is caused by a disaster that kills off most individuals in a population

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 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

changes in a gene pool over time

• Evolution

• Gene

• Mutation

• Genetic drift

change in a gene pool because of chance

• Evolution

• Gene

• Mutation

• Genetic drift

humans breed organisms together to achieve particular genetic traits

• Natural Selection

• Speciation

• Extinction

Which of the following best describes a gene pool?

• The total genetic information within a population

• A collection of genes in a laboratory

• The genetic makeup of an individual

• A group of similar species

What is the primary effect of a small gene pool on a population?

• Increased genetic diversity

• Decreased genetic diversity

• No effect on genetic diversity
