allopatric speciation happens when a physical barrier divides two populations of the same species and sympatric speciation happen when no physical barrier divides the member of a population, but methods such as polyploidy (chromosome doubling) do not let the members of the species have fertile offspring, 2 species are formed (the parental normal species and the divergent species polyploids).
Lesson Summary. Though not common, sympatric speciation is an important evolutionary process that can separate a species into two new ones. This is a relatively uncommon form of speciation, though it has been observed in hawthorn flies and orcas.ympatric speciation occurs if interactions are so limited between these groups that mating no longer occurs between them. Each new population of flies will have genetic variation in its gene pool, which is the collective genetic information for the group.
