Abstract
We used fluorescence in situ hybridization (FISH) to prepare a cytogenetic framework map of 21 polymorphic markers that had been used previously to construct a genetic linkage anchor map of chromosome 5. In addition, we localized 49 other markers that have been genotyped on CEPH families. This study demonstrates that FISH can be used to confirm genetic linkage data, and that it can provide a means of determining the cytogenetic locations and relative order of markers whose order could not be assigned by genetic linkage analysis alone. The cytogenetic map prepared by FISH may help to identify probes of interest for regional mapping studies.
