Karyotyping refers to use of a microscope to examine the size, shape, And number of Chromosomes in a sample of body cells. Extra, missing, Or abnormal positions of chromosome pieces can cause problems with a persons growth, development, and body functions.
In karyotyping, the chromosomes in a cell are stained with a dye to make the bands of each chromosome visible. Banding helps show differences in structure among the chromosomes and helps arrange them into pairs. The chromosomes are then photographed through the microscope. The information also can be entered into a computer that displays a picture (karyotype) of the chromosomes arranged in a specific order, from the largest to the smallest.
