Answer: Yes
During experiment it is required to distinguish and located the position of chromosomes and hence they are coloured using flouroscent dyes.
For this purpose Fluorescence In Situ Hybridization (FISH) technique is used and specific DNA sequences on chromosomes is seen.
These procedures use fluorescent probes to detect DNA sequences, and the process is known as FISH (fluorescence in situ hybridization). Many FISH procedures are available in cytogeneticists, which is use to diagnose many types of chromosomal abnormalities in patients.
Infact, in DNA fingerprinting , floroscent probes and use to find similarity and disimilarity in the given sample.
