Evolution of Populations Quiz

What is the definition of evolution in genetic terms?

• The formation of a new species

• The development of certain traits

• A change in the frequency of alleles in a population over time

• The process of speciation

What is the Hardy-Weinberg principle?

• The process of speciation

• The formation of a new species

• Allele frequencies will remain constant unless factors cause those frequencies to change

• A change in the frequency of alleles in a population over time

Identify and describe the ways in which reproductive isolation can occur.

• Stabilizing selection, Directional selection, Diversifying selection

• Natural selection, Genetic equilibrium, Gene pool

• Genetic recombination, Lateral gene transfer, Mutation

• Behavioral isolation, Geographical isolation, Temporal isolation

What are the sources of genetic variations found in populations?

• Mutation, Genetic recombination, Lateral gene transfer

• Natural selection, Genetic equilibrium, Gene pool

• Allele frequencies, Gene combinations, Genetic equilibrium

• Stabilizing selection, Directional selection, Diversifying selection

What occurs when two populations no longer interbreed, leading to the production of new, distinct species?

• Reproductive isolation

• Genetic recombination

• Lateral gene transfer

• Natural selection

What is the process called when species reproduce and split into two or more species?

• Genetic equilibrium

• Speciation

• Natural selection

• Mutation

What is the effect of mutations on allele frequencies in a population?

• The process of speciation

• A change in the frequency of alleles in a population over time

• Remain constant unless factors cause those frequencies to change

• Cause a change in allele frequencies and can cause evolution to occur

What is lateral gene transfer?

• The formation of a new species

• Passing genes from one organism to another (not including the offspring)

• The process of speciation

• A change in the frequency of alleles in a population over time

What is the process of adaptation to the local environment in a population called?

• Speciation

• Natural selection

• Genetic recombination

• Reproductive isolation

What occurs when there is no natural selection in a population?

• The formation of a new species

• The process of speciation

• Allele frequencies will remain constant unless factors cause those frequencies to change

• Genetic equilibrium is disrupted
