crossing over may result in to

Options

A. Gene mutation
B. Genomatic mutation
C. Genetic recombination
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Crossing Over**:
- Crossing over is a genetic process that occurs during meiosis, specifically in the pachytene stage of prophase I. It involves the exchange of genetic material between non-sister chromatids of homologous chromosomes.

2. **Location of Crossing Over**:
- This process occurs during meiosis I, which is essential for sexual reproduction. It allows for the mixing of genetic information from both parents.

3. **Result of Crossing Over**:
- The primary result of crossing over is the formation of new genetic combinations. This means that the offspring will have a mix of traits from both parents, leading to genetic diversity.

4. **Distinguishing from Mutation**:
- It is important to note that crossing over is different from mutation. Mutations are changes in the base sequences of genes, often caused by mutagens (chemical, physical, or biological agents). Crossing over does not cause mutations; instead, it rearranges existing genetic material.

5. **Conclusion**:
- Therefore, the correct answer to the question "crossing over may result in" is the formation of new genetic combinations.

**Final Answer**: Crossing over may result in new genetic combinations.
