Chromosome are classified into four basic term, 

Chromosome
A) Metacentric chromosome	i) centromeres present at the end of the chromosome
B) Submetacentric chromosome	ii) chromomere near the end of the chromosomes
C) Acrocentric chromosome	iii) Centromere in the middle of the chromosome and divides the chromosome into two equal arms.
D) Telocentric chromosome	iv) The centromere is present near the middle and divides the chromosome into two unequal arms

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
