Karyotyping
They use a technique called FISH (fluorescent in situ hybridization). No one cuts out and lines up chromosomes any more. A fluorescent tag specific for the chromosomes usually involved in human aneuploidies that survive until birth (X, Y, 13, 18, 21). In Kleinfelter's, one Y will light up in addition to two spots each for X, 21, 13, and 18. In this case, the extra X chromosome leads to a partially feminized phenotype and may be linked to other health problems.

Karyotyping. That will display the chromosomes the individual has, in order. Doubled chromosomes are very easy to spot, and the process was used to determine true gender of Olympic athletes where it was suspect.

Karyotyping.
They line up the picture cut-outs of chromosomes and notice that there is an extra X.

Karyotyping, to show X-X-Y.
