Assertion (A): Sexual reproduction increases genetic diversities and plays a role in origin of new species.
Reason (R): Sexual reproduction involves formation of gametes and fusion of gametes.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.

Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Sexual reproduction increases genetic diversities and plays a role in the origin of new species.
Reason (R): Sexual reproduction involves the formation of gametes and fusion of gametes.

Explanation:
Sexual reproduction is a mode of reproduction that involves the fusion of gametes, which are specialized cells involved in sexual reproduction. This process leads to the formation of offspring with unique combinations of genetic traits. Let's break down the assertion and reason to understand their relationship.

Assertion (A): Sexual reproduction increases genetic diversities and plays a role in the origin of new species.
Sexual reproduction is known to increase genetic diversity within a population. This is because during sexual reproduction, genetic material from two different individuals combines to form offspring. The offspring inherit a unique combination of genes from both parents, resulting in increased genetic variation. This genetic diversity is essential for the survival and adaptation of a species to changing environments. Additionally, sexual reproduction can lead to the origin of new species over time through the accumulation of genetic differences.

Reason (R): Sexual reproduction involves the formation of gametes and fusion of gametes.
The process of sexual reproduction involves the formation of specialized cells called gametes. In most organisms, gametes are produced through a process called meiosis, which results in the formation of haploid cells (cells with half the number of chromosomes). These haploid gametes, such as sperm and eggs, carry only one set of chromosomes. During sexual reproduction, the gametes from two different individuals combine through a process called fertilization or fusion. This fusion results in the formation of a zygote, which is a diploid cell (cell with a full set of chromosomes). The zygote then develops into an offspring with a unique combination of genetic traits inherited from both parents.

Conclusion:
Both the assertion and the reason are true, and the reason correctly explains the assertion. Sexual reproduction does increase genetic diversities due to the combination of genetic material from two individuals during the fusion of gametes. This genetic diversity plays a crucial role in the origin of new species over time. Therefore, option 'A' is the correct answer.
