... Having entire extra sets of chromosomes, such as 2n or 4n, is known as polyploidy and is normal in plants. Polyploidy is responsible for unusually large and brilliantly colored flowers. Aneuploidy and polyploidy both result from nondisjunction, where homologous pairs fail to separate during meiosis ...
