Which human chromosomes are sub Metacentric?

A chromosome with equal chromosomal arms is termed metacentric chromosome. In humans, several chromosomes are submetacentric: chromosome 2, chromosome 4, chromosome 5, chromosome 6, chromosome 7, chromosome 8, chromosome 9, chromosome 10, chromosome 11, chromosome 12, chromosome 17, chromosome 18 and X chromosome.

What groups of chromosomes are Acrocentrics in the human karyotype?

Robertsonian Translocations

There are six acrocentric chromosomes in the human genome: 13, 14, 15, 21, 22, and the Y chromosome. A Robertsonian event usually results in a genetic complement of 45 chromosomes due to the fusion of two long (q) chromosome arms and the loss of the corresponding two short arms.

On the basis of the location of the centromere, chromosomes are classified into four types: metacentric, submetacentric, acrocentric, and telocentric.
