Question

Assertion (A): By mutations genetic variations are created resulting in a new trait not found in the parental type.
Reason (R): Plants having desirable characters will be selected after inducing mutations with chemicals or radiation.

• A. A and R are correct. R is the correct explanation of A
• B. A and R are correct. R is not the correct explanation of A
• C. A is correct but R is incorrect
• D. A is incorrect but R is correct

Hint:

When utilizing induced mutations for crop improvement, it is vital to conduct thorough screenings to identify and propagate only those mutations that confer beneficial traits.

Answer 1

The Correct Option is A

Assertion (A): Mutations can indeed create genetic variations by introducing changes in the DNA sequence. These changes can result in new traits that were not present in the parental type, contributing to genetic diversity.
Reason (R): Inducing mutations through chemicals or radiation is a common technique used in plant breeding. By doing so, new variations (traits) are created, and plants with desirable traits are selected for further breeding.
Thus, both Assertion (A) and Reason (R) are correct, and Reason (R) correctly explains Assertion (A). 
Therefore, the correct answer is Option (1).
