The following results were obtained by a scientist who crossed the F₁ generation of pure-breeding parents for round and wrinkled seeds.Dominant trait      Recessive trait      No. of F₂ offspringRound seeds        Wrinkled seeds            7524From these results, it can be concluded that the actual number of round seeds he obtained was:(a) 1881      (b) 22572      (c) 2508      (d) 5643

During mono-hybrid cross (cross with single characteristics, the shape of seed), the ratio of round seeds to wrinkled seed in F2 generation is 3:1, that is out of 4 seeds, 3 seeds will be round and 1 will be wrinkled.

Thus, out of 7524 F2 generation offsprings, the number of round seeds will be calculated as follows:

Out of 4 seeds, 3 seeds are round.

Out of 7524, number of round seeds = (7524 X 3) / 4 

                                                                   = 5634.
