Question

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 offspring

Round seeds Wrinkled seeds 7524

From these results, it can be concluded that the actual number of round seeds he obtained was:

Solution

(d) 5643
The round and wrinkled seeds will be obtained in the ratio 3:1.
$Number of round seeds obtained will be = \frac{7524 \times 3}{4} = 5643$
