Quizplus · Accepted Answer

Polyploidy, or having multiple sets of chromosomes, can occur suddenly in plants due to errors in cell division. This can result in a new species that is reproductively isolated from the parental population, as it cannot interbreed with it due to differences in chromosome number. This can happen within a few generations.
