### Step-by-Step Solution:
1. **Understanding Paracentric Inversion**:
- Paracentric inversion is a type of chromosomal rearrangement where a segment of a chromosome is inverted, but the centromere is not included in the inverted segment.
2. **Identifying the Chromosomal Structure**:
- Consider a chromosome with a centromere and several genes. For example, let's label the genes as A, B, C on one side of the centromere and D, E, F on the other side.
3. **Inversion Process**:
- In paracentric inversion, if we take the segment containing genes A, B, and C and invert it, the sequence will change. The new order will be C, B, A followed by the centromere and then D, E, F.
4. **Characteristics of Paracentric Inversion**:
- The key characteristic of paracentric inversion is that the centromere remains outside the inverted segment. This means that the inversion does not involve the centromere at all.
5. **Differentiating from Pericentric Inversion**:
- In contrast, pericentric inversion involves the centromere. For example, if we inverted the segment that includes genes B and C while involving the centromere, the sequence would change to A, C, B, D.
6. **Conclusion**:
- Based on the definition and characteristics of paracentric inversion, we can conclude that the correct statement regarding paracentric inversion is that the inverted segment does not carry the centromere.
### Final Answer:
The correct option regarding paracentric inversion is that the inverted segment does not carry the centromere.
