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).
In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organisms whose ranges overlap or are even identical, so that they occur together at least in some places. If these organisms are closely related (e.g. sister species), such a distribution may be the result of sympatric speciation.Etymologically, sympatry is derived from the Greek roots ÏÏÎ½ (together, with) and ÏÎ±ÏÏÎ¯Ï (homeland or fatherland).he polyploidal offspring occupy the same environment as the parent plants (hence sympatry), but are reproductively isolated. A rare example of sympatric speciation in animals is the divergence of resident and transient Orca forms in the northeast Pacific.
