The chromosomal constitution of a cell is called karyotype. For human cytogenetically normal individuals the karyotype is composed of 46 chromosomes ( 23 pairs of autosomes and a pair of sexual ones, XX or XY).

Cytogeneticists arrange the chromosomes in a manner that is called karyogram. A karyogram shows the chromosomes and point out their abnormalities if there is any. These abnormalities can be due to alterations in the number (numerical abnormalities) or in the structure (structural abnormalities) of the chromosomes.

During this on line class you are going to to simulate and learn how to produce a karyogram.
