Given below are two statements.
Statement-I: Genetic diversity is the diversity in number and type of genes as well as chromosomes present in the same species and variations in the genes and their alleles.
Statement-II: Species diversity deals with variety of species as well as number of individuals of different species observed in an area.
In light of above statement, select the correct answer from the options geiven below.

A Both Statement-I and Statement-II are correct.
B Both Statement-I and Statement-II are incorrect.
C Statement-I is correct and Statement-II is incorrect.

(D) Statement-I is incorrect and Statement-II is correct.

Step-by-step Solution

Detailed explanation

Genetic diversity is Intrapesific diversity. It is diversity in number and types of genes a well as chromosomes present in different species and also variation in their genes and alleles in the same species.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
