Answer 25

Chromosomal mutation is involving the change in chromosome structure. The changes in structure will change the composition or location allele.

Deletion - a segment of chromosome is broken off and lost.

Inversion - a segment of chromosome is broken off and reattach itself in inverted position.

Duplication - a segment of chromosome is copied twice, resulting in extra allele.

Translocation - a segment of chromosome is broken off and reattach at different point.
