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 ______  

Options

  • 1881

  • 22572

  • 2508

  • 5643

MCQ

Solution

5643

Explanation:

The round and wrinkled seeds will be obtained in the ratio of 3:1. 

The number of round seeds obtained will be `(7524 xx 3)/4= 5643`.
