Explanation:

Polyploidy occurs when an organism has extra sets of chromosomes, forming a new species within the same geographic area as the parent population. This fits the definition of sympatric speciation, where new species arise without geographic isolation. Parapatric speciation involves adjacent populations, allopatric requires geographic separation, and prezygotic/postzygotic refer to reproductive barriers, not speciation modes.

Answer:

sympatric
