Final answer:
Gregor Mendel chose to study the traits of pea plants because they have easily identifiable characteristics and grow quickly. His study of pea plants and his discoveries about inheritance revolutionized the field of genetics.
Step-by-step explanation:
Gregor Mendel chose to study the traits of pea plants because they have easily identifiable characteristics. For example, pea plants can either be tall or short, making it easy to observe and study this trait. Additionally, pea plants grow quickly, allowing Mendel to conduct a large number of experiments in a short amount of time.
Mendel's study of pea plants and his discoveries about how traits are passed from parents to offspring formed the foundation of the study of genetics. His experiments with pea plants demonstrated the existence of dominant and recessive traits and established the principles of inheritance. Mendel's work revolutionized our understanding of genetics and laid the groundwork for future research in this field.
