title: A polymorphic locus on the long arm of chromosome 20 defined by two probes from a single cosmid.
abstract: Two probes from the random human cosmid c1-37 detect restriction fragment length polymorphisms in humans. The loci revealed by these probes are in linkage equilibrium and constitute a compound polymorphic locus with a polymorphism information content of 0.54. A somatic cell hybrid panel has been used to map the probes to chromosome 20; in situ hybridization studies confirm this localization and indicate that the locus is on 20q13. This is the first polymorphic locus to be assigned to the long arm of chromosome 20.
