ABSTRACT:
The invention is a method for detecting whether an organism is homozygous or heterozygous in a target nucleotide. The method combines hybridization of two differently labelled probes A and B on either side of a restriction site, restriction endonuclease digestion, and detection of the labels in the resulting digest. If an organism is: homozygous then the labels will be present in the ratio 1:1 or 1:0; or if heterozygous then the labels will be present in the ratio 1:2. Either immobilized array technology or electrophoretic separation may be used.
