Clones are defined as a group of morphologically and genetically identical individuals. In the process of asexual reproduction,only one parent is involved to produce morphologically and genetically similar off spring from parents and are thus called clones

Directions: In the following questions, a statement of assertion (A) ...
Assertion: Clones are offspring of an organism formed by asexual reproduction.
Reason: Clones have exact copies of DNA as their parents.
The correct answer is option B: Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
Explanation:
Asexual reproduction is a type of reproduction that involves only one parent, and the offspring produced are genetically identical to the parent. Clones are individuals that are produced through asexual reproduction, and they have the exact copies of the parent's DNA.
Assertion (A): Clones are offspring of an organism formed by asexual reproduction.
This statement is true. Clones are the offspring of an organism that reproduces asexually. In asexual reproduction, a single organism gives rise to one or more genetically identical offspring without the involvement of gametes or fertilization.
Reason (R): Clones have exact copies of DNA as their parents.
This statement is also true. Clones are produced by the process of mitosis, where the parent's DNA is replicated and passed on to the offspring. As a result, the offspring have the same genetic information as the parent, making them genetically identical.
Explanation of the Reason:
The reason given is not the correct explanation of the assertion. While it is true that clones have exact copies of DNA as their parents, this fact alone does not explain why clones are offspring of an organism formed by asexual reproduction. The reason fails to provide a direct link between the genetic similarity and the mode of reproduction.
In asexual reproduction, the offspring are genetically identical to the parent because they are produced through processes like binary fission, budding, or vegetative propagation. These processes do not involve the fusion of gametes or the exchange of genetic material, resulting in offspring that are clones of the parent.
Therefore, while both the assertion and reason are true, the reason does not correctly explain the assertion. Hence, the correct answer is option B: Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
