Final answer:
Polyploidy is commonly found in plants. Polyploid plants tend to be larger and more robust than plants with the correct number of chromosome sets.

Polyploidy is commonly found in plants. It occurs when an individual has more than the correct number of chromosome sets. Polyploidy is rare in animals, with only a few examples among certain species. In contrast, polyploidy is very common in the plant kingdom and polyploid plants tend to be larger and more robust than plants with the correct number of chromosome sets.
