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).
Sympatric speciation. Definition. noun. A speciation in which new species evolve from a single ancestral species while inhabiting the same geographic region. Supplement. Sympatric speciation is more common in plants. For instance, parent plants produce offspring that are polyploid.Hence, the offspring live in the same environment as their parents but are reproductively isolated.ympatric speciation is more common in plants.
