Speciation and Genetic Drift

The combined genetic information of all memebers of a particular population forms a:

• gene pool

• allele frequency

• phenotype

• population

Temporal isolation occurs when two different populations:

• develop different mating behavior

• become geographically separated

• reproduce at a different times

• interbreed

When two populations no longer interbreed, what is the result?

• genetic equilibrium

• stabilizing selection

• genetic drift

• reproductive isolation

Situation in which allele frequencies change as aresult of the migration of small subgroup of a population is known as:

• founder effect

• genetic bottleneck

• random mating

• natural selection

Introduce new alleles

• Small population size

• Non random mating

• Mutations

• None
