Chromosome mutations can be grouped into three basic categories:

I) Chromosome rearrangements

II) Aneuploidy

III) Polyploidy

these mutation alters the number and structure of chromosomes such as,

 a) One or more individual chromosomes are added or deleted

b) The loss of a chromosomal segment

c) A piece of a chromosome might be duplicated, deleted, or inverted

d) One or more complete sets of chromosomes are added

e) In which one or more copies of a DNA segment is produced
