Answer 1

Insertion:- The insertion (also called insertion mutation) is the addition of one or more base pairs of nucleotides to a DNA sequence. Despite of the slipping of DNA polymerase this may also happen in microsatellite regions. Inserts may be incorrectly inserted from one base pair into a DNA sequence to a section of one chromosome inserted into another, anywhere in size.

Deletion :- In genetics, a deletion (also known as gene deletion, malfunction, or deletion mutation) (sign: random) is a mutation (genetic aberration) in which part of a chromosome or DNA sequence is omitted during replication of DNA. You can delete any number of nucleotides, from a single base to a whole piece of chromosome.

Gene duplication :- A major mechanism through which new genetic material is produced during molecular evolution is gene duplication (or chromosomal duplication or gene amplification). This may be characterized as any duplication of a DNA region containing a gene.
