Assertion: In a monohybrid cross, we study two characters.
Reason: In a monohybrid cross, alleles exhibit dominant recessive relationship.

A

Both Assertion and Reason ae true and the Reason is a correct explanation of the Assertion

B

Both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion

C

Assertion is true, but the Reason is false

D

Assertion is false, but the Reason is true

Text Solution

Verified by Experts

The correct Answer is:
D
In monohybrid cross, single character each controlled by a single pair of genes or alleles are considered. In `F_(2)` -generation, monohybrid crossshows 3 : 1 ratio between dominant character and recessive character.
