Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
Y_Kistochka [10]
Deletion is when a part of the chromosome is deleted. (Removed)
Insertion is when part of our chromosome has an extra bit added to it.
Translocation Is when one part of the chromosome is moved to another chromosome.

The correct answer is inversion, to invert means to turn upside down. So when part of the chromosome is taken off but attached backwards (turned upside down) we call it inversion

Hope that makes sense
