• variation within a species

• extinction of the species

• various different speices

• no change in the genes of an organism

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.

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

Tradescantia ohiensis, a plant also known as bluejacket and its relative, T. subaspera have similar reproductive mechanisms but do not mate, as one species lives in sun while the other lives in shade.

• Geographic isolation

• Behavioral isolation
