Answer: Interstitial Deletion
Explanation:
The chromosomes can be broken down when they are stuck by the ionizing radiation.
The terminal deletion takes place when the two breaks are induced at the terminal part and the rest part of the chromosomes are attached or rejoins to the main chromosomes with the acentric part being lost.
This is called as the interstitial deletion of the chromosomes. This is a type of defect which causes mutation in the body.
