Q. Illegitamte crossing over is another terma for

Options

A. a) Transition
B. b) Transversion
C. c) Reciprocal transloction
D. d) None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for another term that is synonymous with "illegitimate crossing over."

2. **Defining Key Terms**:
- **Transition**: This is a type of point mutation where a purine nucleotide is replaced by another purine (A ↔ G) or a pyrimidine nucleotide is replaced by another pyrimidine (C ↔ T).
- **Transversion**: This is another type of point mutation where a purine is replaced by a pyrimidine or vice versa (A or G ↔ C or T).
- **Reciprocal Translocation**: This involves the exchange of segments between two non-homologous chromosomes. It is similar to crossing over but occurs between chromosomes that are not homologous.

3. **Identifying the Correct Answer**: Among the options provided:
- Transition and transversion are types of point mutations and do not relate to crossing over.
- Reciprocal translocation is the only term that describes an exchange similar to crossing over but occurs between non-homologous chromosomes. This is also referred to as "illegitimate crossing over."

4. **Conclusion**: Therefore, the term that is synonymous with "illegitimate crossing over" is **reciprocal translocation**.

**Final Answer**: The correct option is **C) Reciprocal Translocation**.
