Genetic variations affect the production of the drug reserpine in the medicinal plant Rauwolfia vomitoria growing in different Himalayan ranges. What kind of diversity does it indicate ?
(a) Species diversity
(b) Genetic diversity
(c) Ecological diversity
(d) None of these

Options

A. Species diversity
B. Genetic diversity
C. Ecological diversity
D. None of these

Explanation

To solve the question regarding the type of diversity indicated by genetic variations affecting the production of the drug reserpine in the medicinal plant Rauwolfia vomitoria, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question mentions that genetic variations affect the production of a drug (reserpine) in the plant Rauwolfia vomitoria, which is found in different Himalayan ranges.

2. **Identify the Key Term**: The key term in the question is "genetic variations." This indicates that we are looking at differences at the genetic level within the same species.

3. **Analyze the Options**:
- **(a) Species diversity**: This refers to the variety of different species within a particular habitat or ecosystem. It does not focus on genetic differences within a species.
- **(b) Genetic diversity**: This refers to the variety of genes within a species, including variations in alleles and genetic makeup that can lead to differences in traits, such as drug production.
- **(c) Ecological diversity**: This refers to the variety of ecosystems in a given place, which is not relevant to the genetic variations mentioned.
- **(d) None of these**: This option suggests that none of the previous categories apply, which is not the case here.

4. **Select the Correct Answer**: Given that the question specifically mentions genetic variations affecting drug production, the correct answer is **(b) Genetic diversity**. This is because the variations in genes within the same species (Rauwolfia vomitoria) lead to differences in the production of reserpine.

### Final Answer:
(b) Genetic diversity
