Q1How many true-breeding pea plant varieties were used by Gregor Mendel for his experiment on artificial or cross-pollination?
Explanation
Gregor Mendel studied seven contrasting pairs of traits in pea plants. For those seven pairs, he used fourteen true-breeding varieties, because each trait pair had two alternative forms. Seven refers to the number of character pairs, not the number of true-breeding varieties. Eight and ten do not correspond to Mendel’s standard pea-plant experimental design. Hence, when the question asks for true-breeding pea plant varieties used in artificial or cross-pollination experiments, the correct number is fourteen.
