Cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as

Options

A. in situ conservation of biodiversity
B. Advanced ex - situ conservation of biodiversity
C. in situ conservation by sacred groves
D. in situ cryo - conservation of biodiversity

Answer

To solve the question regarding the cryopreservation of gametes of threatened species in viable and fertile condition, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Cryopreservation**:
- Cryopreservation is a technique used to preserve cells, tissues, or any biological constructs by cooling them to sub-zero temperatures.
- This process allows for the long-term storage of gametes (sperm and eggs) while maintaining their viability and fertility.

**Hint**: Remember that cryopreservation involves freezing biological materials to preserve them for future use.

2. **Identifying the Context**:
- The question specifically refers to threatened species, indicating a focus on conservation efforts.
- The preservation of gametes is crucial for the survival of these species, allowing for future breeding and genetic diversity.

**Hint**: Consider the implications of preserving genetic material for endangered species.

3. **Ex-situ Conservation**:
- Cryopreservation is a form of ex-situ conservation, which means that the preservation occurs outside the natural habitat of the organisms.
- This method contrasts with in-situ conservation, where species are protected in their natural environments.

**Hint**: Differentiate between in-situ (natural habitat) and ex-situ (artificial environment) conservation methods.

4. **Advanced Ex-situ Conservation**:
- Cryopreservation can be classified as advanced ex-situ conservation because it employs sophisticated techniques to ensure the viability of gametes.
- This method allows for the preservation of genetic material that can be used to restore populations in the future.

**Hint**: Think about how advanced techniques enhance traditional conservation methods.

5. **Evaluating the Options**:
- The question provides multiple-choice options. We need to identify which option correctly describes cryopreservation.
- The correct answer is "advanced ex-situ conservation of biodiversity," as it accurately reflects the nature of cryopreservation.

**Hint**: Cross-reference the options with your understanding of conservation methods.

### Final Answer:
The cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as **advanced ex-situ conservation of biodiversity**.
