Question

Quizplus · Accepted Answer

Polyploidy, or the duplication of an organism's entire set of chromosomes, is a common mechanism for sympatric speciation in plants. This can occur due to errors in cell division during meiosis, resulting in a new plant species that can no longer interbreed with the parent species. Geographic isolation, spontaneous mutation, punctuated equilibrium, and disruptive selection are all mechanisms for speciation, but they are less common in plants than polyploidy.
