Answer:
centromere
Step-by-step explanation:
Chromosomal inversions, as its name suggests, are alterations that occur when a portion of the chromosome splits off but rejoins the chromosome in reverse. The genetic material remains the same, however, the disposition of information occurs in a exchanged manner.
We can classify chromosomal inversion into two types:
- Pericentric: Pericentric inversion occurs when the region undergoing inversion surrounds the centromere.
- Paracentric: Paracentric inversion occurs when the inverted region does not involve the centromere.
