Abstract: <P>PROBLEM TO BE SOLVED: To make individual person identification by using a DNA judgement as having a higher sensitivity and higher accuracy by providing an index of the combinations of polymorphs effective for identifying the individual from an analysis of the sequences of an mtDNA of a large number of people and by solving problems such that although the use of the polymorph of nuclear DNA for the identification of the individual exhibits a high individual identification capability, it is impossible to detect unless each of the DNAs is obtained in a sufficient amount and in a good state, and on the other hand, to use the polymorph of the mtDNA for the identification of the individual, there is no index for the selection of the polymorphs and the method has to depend on a D-LOOP region where polymorphs appears frequently.  <P>SOLUTION: The more effective individual identification can be done by analyzing the combinations of the polymorphs according to the index for selection of the mtDNA. Also, the individual identification of a higher accuracy can be done by analyzing the polymorphs in the outside of the D-LOOP region in addition to the sequences of the polymorphs at the D-LOOP region which is conventionally performed. By analyzing the combinations of the polymorphs in the outside of the D-LOOP region, an efficient gene type classification can be done, and is especially effective in systematic genetic analyses. Further higher accuracy individual identification can be performed by combining the above method with a component analysis method, or spectrometric analysis or form observation method.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
