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).
Examples of sympatric speciation are often disputed because they must show convincing evidence of species descending from the same ancestral species, the reproductive isolation of the group, and of allopatry not causing the speciation.
