Bacterial conjugation:

Options

A. is a rare form of genetic recombination
B. is a virus mediated transfer of gentic material
C. is incomplete transfer of genetic material
D. involves meiosis and synagamy

Answer

**Step-by-Step Solution:**

1. **Definition of Bacterial Conjugation**: Bacterial conjugation is a process where one bacterium transfers genetic material to another through direct contact. This is a form of genetic recombination.

2. **Role of Pilus**: The pilus (or conjugative pilus) is a structure that facilitates this direct contact between two bacterial cells. It draws the two bacteria together, allowing for the transfer of genetic material.

3. **Donor and Recipient Bacteria**: In this process, one bacterium acts as the donor (which has the F factor) and the other acts as the recipient (which does not have the F factor). The donor bacterium transfers its genetic material to the recipient.

4. **Mechanism of Transfer**: The transfer of DNA occurs through the pilus, which forms a mating pair between the two bacterial cells. This allows for the exchange of genes.

5. **Nature of Conjugation**: Bacterial conjugation is considered a parasexual mode of reproduction, as it does not involve the typical sexual reproduction processes like meiosis or synagamy.

6. **Conclusion**: Based on the characteristics of bacterial conjugation, it is classified as a rare form of genetic recombination.

**Final Answer**: The correct option is that bacterial conjugation is a rare form of genetic recombination.
