Question

Quizplus · Accepted Answer

Formation of a tetraploid plant from two different diploid parental species of plants is an example of sympatric speciation, where reproductive isolation occurs within the same geographical region. This can happen through various mechanisms including polyploidization, hybridization, and ecological adaptation. Postzygotic and prezygotic speciation involve mechanisms that lead to reproductive isolation before or after fertilization, respectively. Parapatric and allopatric speciation involve geographical barriers to gene flow.
