Karyotyping: Human Karyotype Analysis
Laboratory Technique of Karyotyping
Karyotyping is the microscopic analysis of the chromosomes of a cell in metaphase, the stage of maximum DNA compression. The chromosomes are numbered according to size and examined. The difference in chromosome staining results from euchromatin and heterochromatin and produces a characteristic banding pattern. The banding pattern of the chromosomes enables identification of individual chromosomes and a possible numerical chromosome aberrations [Fig normal human karyotype].
