Final answer:
Mendel chose purebred plants to ensure consistency in traits for his experiments, aiding in his genetic discoveries.
Explanation:
Gregor Mendel chose to use purebred plants in his experiments because they always produce offspring with the same phenotype when self-fertilized. By using purebreds, Mendel could ensure that he was working with plants that exhibited one form of a trait, which helped him establish the principles of genetics.
