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

• gene flow
• gene pool
• allele

When birds cannot interbreed because they have different mating songs, they are separated by

• Temporal isolation
• Behavioral isolation
• Geographic isolation
• Habitat isolation

 In a small population, a random change in allele frequency is called

• Genetic drift
• Natural selection
• Adaptive radiation
• Evolution

• Geographic isolation
• Habitat isolation

When individuals with either extreme version of a trait have a greater fitness than those with the average version; this is a type of selection called

• stabilizing selection
• directional selection
• sexual selection
• disruptive selection
