Gregor Mendel chose pea plants (Pisum sativum) for his groundbreaking genetic experiments.
Which of the following is a valid reason why pea plants were highly suitable for his research?
They have several clearly observable, contrasting characteristics with distinct traits.
They can only reproduce asexually, ensuring all offspring are genetically identical clones.
They produce very few offspring, making it easier to count and track individuals.
Their generation time is several years, allowing detailed observation of gradual growth.
