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

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`.

If we pure-bred tall (dominant) pea plant with pure-bred dwarf (recessive) pea plant we will get pea plants of F1 generation. If we now self-cross the pea plant of F1 generation, then we obtain pea plants of F2 generation.

(a) What do the plants of F2 generation look like?

(b) State the ratio of tall plants to dwarf plants in F2 generation.

(c) State the type of plants not found in F1 generation but appeared in F2 generation, mentioning the reason for the same.


Assertion: When pure breed tall plants are crossed with pure breed short plants, all the plants in F1 progeny are tall. When the tall plants of F1 progeny are crossed, short plants re-appear in F2 progeny.
