All the possible gene combinations in a population.

• allele

• gene pool

• genome

• mitosis

Organisms of the same species can no longer interbreed therefore creating two species.

• Gene Pool

• Genetic Drift

• Gene Frequency

• Speciation

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation
• Adaptation
• Behavior
• Environment

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction

The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.
• The acquired traits of a population.
• Hair color and eye color
• Attractive features.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.
