Acrocentric Chromosomes
Acrocentric chromosomes have the centromere visible from the center. This causes a very long and very short arm. These are present in humans.
Submetacentric Chromosomes
Submetacentric chromosomes have the centromere a little away from the center. These are present in humans, such as chromosome 2.
Metacentric Chromosomes
Metacentric chromosomes have the centromere located in the center. These are present in humans, such as chromosome 19.
