| Abstract: | Recent finding in highly effective DNA probes for RFLP testing (of hypervariable minisatellite DNA type) has led to the invention of DNA fingerprinting--the new technique of great value for identification of individuals, establishing biological kinship and studies in population genetics. We anticipate that DNA fingerprinting procedure with M13 phage DNA as a probe which we have developed earlier, makes it possible to apply new approach in genetic analysis--establishing, whether or not a particular locus is associated with the inheritance of genetic disease, by comparing the whole restriction fragment data from affected and unaffected animals. In this work, using the method described we characterized the Kroushynsky-Molodkina rat strain with hereditary disposition for epileptic attacks and performed comparative fingerprint analysis of these defective and normal rat genomes. The data obtained may hold some promises for further seeking the particular defective gene. |
