Types of Mutation
Mutations can be classified in various ways depending on the cause of the mutation, its effect on the function of the gene product or the kind of changes to the structure of the gene itself.

Point mutation can be deletion, insertion, substitution
Other type of mutation is chromosomal aberration
which can be chromosomal structural mutation and chromosomal number mutation.
it is further divided into deletion, inversion, translocation, duplication, Euploidy, Aneuploidy, monosomy, Nullisomy or nullosomy, Trisomy, Tetrasomy, Triploid, Tetraploid, polyploid,
Spontaneous mutation, Induced mutation, germline mutation or hereditary mutation, somatic mutation, acquired mutation, de-novo mutation etc.
