The short arm of the chromosome is labeled the “p arm.” The long arm is labeled the “q arm.” The ends of the chromosome are called telomeres. 5. Chromosomes in animal cells are usually in pairs (called diploids or 2n). WebIf the centromere is present near about in the middle of the chromosome, then it is called as metacentric, i.e., chromosomes have equal or almost equal arms. Amphibians possess such chromosomes.
