- 31. Human karyotype preparationmade by means of a banding technique. Each chromosome has a particular pattern of banding that facilitates its identification and also the relationship of the banding pattern to genetic anomalies. The chromosomes are grouped in numbered pairs according to their morphologic characteristics.
