In a plant species, flower colour yellow is dominant over white, and fruit shape round is dominant over elongated. Crossing was performed between two pure one having yellow-flower and round-fruit, and another with white flower and elongated-fruit. About 20 plants survived in F1 progeny. Plants of F1 were allowed to self-fertilize, and about 960 plants survived in F2. If the traits follow Mendelian inheritance, the number of plants would have yellow-flower and round-fruit in F1 and F2 are respectively
