Answer:
Peas have an unusually long generation time.
Explanation:
Mendel's study was about understanding inheritance in Pisum Sativum, popularly called the pea plant. The reason why Mendel chose peas were simple. He chose them because other similar researchers had also used pea plant for their research, and due to the fact that they are easy to grow and are sown yearly. Another reason was because the plant had the ability to self-pollinate. His choice of using peas had nothing to do with the long generation time of the plant.
