Solution:

A karyotype is simply a picture of a person's chromosomes. In order to get this picture, the chromosomes are isolated, stained, and examined under the microscope. Chromosomal disorders can be identified by karyotype but gene disorders cannot be identified by it. Klinefelters syndrome, Down syndrome and Turner syndrome are chromosomal disorders. Rest all are gene disorders.
