Answer» (B) 3 : 1 Yellow round = 9 Yellow wrinkled = 3 Green round = 3 Green wrinkled = 1 From above, i. Yellow coloured seeds = 9 + 3 = 12 Green coloured seeds = 3 + 1 = 4 ∴ Yellow : Green = 12:4 = 3:1 ii. Similarly, Round seeds = 9 + 3 = 12 Wrinkled seeds = 3 + 1 = 4 ∴ Round wrinkled = 12:4 = 3:1 |
