What were mendel's three choices and examples?

Mendel's three key choices in his experiments were the selection of traits, the use of purebred plants, and the choice of pea plants as his model organism. He focused on traits such as flower color, seed shape, and pod color to study inheritance patterns. By using purebred plants, he ensured that the traits would consistently pass down to the next generation, allowing him to observe dominant and recessive traits effectively. Pea plants were chosen for their ease of cultivation and the ability to control pollination.
