The dihybrid cross in pea plant between round yellow (smooth) seeded and wrinkled green seeded plant proves the Mendelian principle of independent assortment. It will produce four phenotypes as follows: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/biology/49946fbd8def409c17d54ca401ce6573-.png" />
