Why have these sympatric pairs not proceeded to the point of irreversible reproductive isolation? One possibility is the limited time frame for their divergence, given ...

3 models for genetic isolation

... these in fact "models?" In your own words explain three models that bring about the genetic isolation of a population • Allopatric and sympatric speciation- Something happens (i.e. geographical isolation, ecological isolation) to a population that isolates the gene flow. The two subpopulations ...
