Inversion without involving the centromere is called

Options

A. Paracentric
B. Monosomy
C. Pericentric
D. Tautomerization

Answer

To answer the question "Inversion without involving the centromere is called," we need to understand the types of chromosomal inversions.

### Step-by-Step Solution:

1. **Understanding Inversion**: In genetics, an inversion is a chromosomal rearrangement where a segment of a chromosome is reversed end to end.

2. **Types of Inversion**: There are two main types of inversions:
- **Paracentric Inversion**: This type of inversion occurs when the inverted segment does not include the centromere.
- **Pericentric Inversion**: This type of inversion includes the centromere in the inverted segment.

3. **Identifying the Correct Type**: Since the question specifically asks for an inversion that does not involve the centromere, we focus on paracentric inversion.

4. **Conclusion**: Therefore, the correct answer to the question is that inversion without involving the centromere is called **paracentric inversion**.
