Abstract
The number of chromosomes over which the genome is distributed and the microscopically visible morphology of these chromosomes form the karyotype (Sect. 2.5). Chromosome morphology traditionally includes the length of the chromosomes, the location of the primary constriction (centromere) and, if present, the secondary constriction (near the NOR). Tertiary constrictions in somatic metaphase chromosomes are occasionally visible and can then be used to specify chromosome segments. They tend to coincide with heterochromatic.
