The following results were obtained by a scientist who crossed the F 1 generation of pure-breeding parents for round and wrinkled seeds. Dominant trait -Round seeds Recessive trait -Wrinkled seeds No. of F 2 offspring -7524 From these results, it can be concluded that the actual number of round seeds he obtained was:

Question

Philoid · Accepted Answer

5643; When Round ‘RR’ and wrinkled ‘rr’ seed bearing plants are crossed, all heterozygous round seed bearing plants are obtained in the F1 generation. When the plants of these F1 generations are cross bred, the F2 generation had round and wrinkled seed bearing plant in the ratio 3:1. (total=4)

Hence, (3/4) * 7524= 5643
