Detailed explanation-1: -Thus 50% of the offsprings will be homozygous round seeded whereas 50% will be heterozygous round seeded plants.
Detailed explanation-2: -The selfing of F1 will give F2 generation, where there will be one homozygous dominant round seed plant (RR), two heterozygous round seed plants (Rr) and 1 homozygous recessive wrinkled seed plant (rr). Phenotypically, there will be 3 round seed plants and 1 wrinkled seed plant. Hence, the correct answer is ‘3:1’.
Detailed explanation-3: -In the F1 generation, 50% of the offspring produced wrinkled seeds.
Detailed explanation-4: -So, the correct option is ‘303 rounded: 301 wrinkled’.
Detailed explanation-5: -When a heterozygous round seeded plant is crossed with a recessive wrinkle seeded plant, the round and wrinkled phenotypes will appear in F, in the ratio.
