Question

Inversion mutation.
Translocation mutation.
Duplication mutation.
Deletion mutation.
Inversion mutation.
Translocation mutation.
Duplication mutation.
Hint:
In an inversion, the chromosomes get rearranged. They get reversed.
The correct answer is: Inversion mutation.
- An inversion is a chromosomal rearrangement in which a segment of a chromosome is reversed end-to-end.
- Inversions occur when a single chromosome splits and rearranges itself. There are two types of inversions: paracentric and pericentric.
- A paracentric inversion does not involve a centromere and both breaks occur in one arm of the chromosome. Pericentric inversions involve centromeres and have breakpoints on each arm.
