Genetic recombination is possible only through

Options

A. Budding
B. Asexual reproduction
C. Sexual reproduction
D. Fragmentation

Answer

**Step-by-Step Solution:**

1. **Understanding Genetic Recombination**: Genetic recombination refers to the process by which genetic material is rearranged during the formation of gametes, leading to genetic diversity in offspring.

2. **Role of Meiosis**: Genetic recombination primarily occurs during meiosis, a type of cell division that reduces the chromosome number by half and leads to the production of gametes (sperm and eggs).

3. **Crossing Over**: A key event in meiosis is crossing over, where homologous chromosomes exchange segments of genetic material. This process is crucial for creating new combinations of alleles.

4. **Heritable Variation**: The genetic variations produced through recombination during meiosis can be passed on to the next generation, leading to heritable variation within a species.

5. **Evaluating the Options**: The question provides several options:
- Budding
- Asexual reproduction
- Sexual reproduction
- Fragmentation

6. **Analyzing Each Option**:
- **Budding**: A form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent. No meiosis occurs.
- **Asexual Reproduction**: Includes methods like budding and fragmentation, where offspring are genetically identical to the parent. No meiosis occurs in these processes.
- **Sexual Reproduction**: Involves the fusion of gametes (sperm and egg) and includes meiosis, allowing for genetic recombination through crossing over.
- **Fragmentation**: Another form of asexual reproduction where an organism breaks into fragments, each capable of growing into a new organism. No meiosis occurs.

7. **Conclusion**: Since genetic recombination is associated with meiosis, the only option that involves meiosis and allows for genetic recombination is **sexual reproduction**.

**Final Answer**: Genetic recombination is possible only through **sexual reproduction**.
