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 lines - one having yellow-flower and round fruit, and another with white-flower and elongated-fruit. About 20 plants survived in \[{{F}_{1}}\] progeny. Plants of \[{{F}_{1}}\] were allowed to self fertilize, and about 960 plants survived in \[{{F}_{2}}\]. If the traits follow Mendelian inheritance, the number of plants would have yellow flower and round fruit in \[{{F}_{1}}\] and \[{{F}_{2}}\] are respectively
