<unk>  (Fluorescent in<unk><unk>  is a cytogenetic technique which can be used to detect and localize the presence or absence of specific DNA sequences on chromosomes. It uses fluorescent probes which bind only to those parts of the chromosome with which they show a high degree of sequence similarity.<unk>  microscopy can be used to find out where the fluorescent probe bound to the chromosome.<unk>  is often used for finding specific features in DNA.  These features can be used in genetic counseling, medicine, and species identification.
