Duplication -
Displaced duplication: In this mutation, the extra segment is located on the same chromosome but at a different location from the normal segment.
Translocation duplication: In this mutation, the extra segment is located on another chromosome which is unrelated to it.
Duplications do not have drastic effects like deletions. But some duplication may have distinct phenotypic effects and may be regarded as mutant allele, e.g. bar duplication in Drosophila. In duplication, the number of copies of genes will increase.
