We have discussed a lot about about chromosomes in previous posts.

| Chromosomes based on position of centromere |
In this post we are limiting our discussion to classification of chromosomes based on position of centromere and function
Based
on Position of Centromere
1.Metacentric: centromere in the
middle forming two equal sized arms
2.Submetacentric: centromere near the middle forming two unequal arms,
one slightly longer than the other
3.Acrocentric:
centromere near the tip forming two unequal
arms, one much shorter (p arm) than the other (q arm)
4.Telocentric: centromere at the tip and a single arm
Based
on function
1.Autosomes: contains genes that controls non-sexual or somatic
characters
2.Sex chromosomes: contains genes that controls sexual characters
