Multiple choice question.
It is equally common in animals and in plants
It is more common in animals than in plants
It is more common in plants than in animals

Answer 1

Polyploidy is more common in plants than in animals. It occurs commonly in plants and is an important aspect in the history and evolution of many crops.

Step-by-step explanation:

The correct statement about polyploidy is that it is more common in plants than in animals.

Polyploidy is a condition in which a cell or organism has an extra set or sets of chromosomes. It occurs commonly in plants and is an important aspect in the history and evolution of many crops. The cultivated forms of wheat, cotton, and tobacco plants are examples of plants that have evolved through polyploidy.

On the other hand, polyploidy is rare in animals and occurs only in a few examples among certain groups of animals, such as flatworms, crustaceans, amphibians, fish, and lizards. Polyploid animals are sterile because meiosis, the process of cell division that produces gametes, cannot proceed normally and instead produces mostly nonviable daughter cells.
