Question

Assertion (A): Genes present in every cell of an organism control the traits of the organisms.

Reason (R): Gene is specific segment of DNA occupying specific position on a chromosome.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

The assertion is true because the genes embedded within the DNA of every cell contain the structural blueprints that dictate and control an organism's physical and physiological traits. The reason is also true and serves as the correct explanation because it defines what a gene functionally is: a precise segment of DNA positioned at a specific locus on a chromosome. Because it occupies this distinct functional position, it can express the proteins that directly govern those specific organismal traits.
