WebThere are four main types of chromosomes: metacentric, submetacentric, acrocentric, telocentric. Metacentric chromosomes are X-shaped, with the centromere in the middle so that the two arms of the chromosomes are almost equal. A chromosome is a metacentric if its two arms are equal or almost equal in length. Several chromosome regions have been defined by convenience in order to talk about gene loci. Most important is the distinction between chromosome region p and chromosome region q. The p region is represented in the shorter arm of the chromosome (p is for petit, French for small) while the q region is in the larger arm (chosen as next letter in alphabet after p).
