• individual
• population
• species
• fossil

Protein sequences in one organism that resemble those of another suggest a 

• coincidence
• lack of evolutionary relationship
• great number of mutations
• shared ancestry

A measure of how commonly a particular allele occurs in a population is known as the 

• gene pool
• allele frequency
• mutation rate
• phenotype

Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)

• mutation
• gene flow
• gene pool
• allele

This increases genetic variation when animals move  from one population to another

• genetic drift
• sexual selection
• bottleneck effect
• gene flow

Five-factors that influences evolution include gene flow, genetic drift, mutation, natural selection and ....

• non-random mating
• controlled mating
• emigration
• immigration

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

What is speciation?

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
• divergence of two or more species from an existing one

two species are in different environments and look very similar.  However, that are not closely related (analogous).  Their resemblance is most likely an example of.

• sexual selection
• temporal isolation
• convergent evolution
• divergent evolution

asexual reproduction produces offspring with

• half of a single parent's genes
• the same genes as the parent
• a mix of genes from two parents
• lots of genetic variation
