And a hybridization probe method, and primers for the identification of organisms by comparative gene analysis, gene which is highly conserved, and coding and non-coding regions of homologues or pseudogenes (57) [Abstract] The present invention, / or is characterized in that the amplified regions functionally significant by using a PCR, then the genotyping and analyzed. Genes are highly conserved, the comparison of the coding and non-coding regions of homologues or pseudogenes, bind to DNA sequences that are highly conserved between species a single oligonucleotide pair is different, so that, for all species Amplification of the gene segments are the same becomes possible. Oligonucleotides, gene regions more or include one having a sequence differences most likely among different species. Determination of the gene sequence of the region of the highly polymorphic in subsequent reaction steps makes it possible to assign a particular species the gene sequences. In a preferred variant of the specific embodiment of the present invention, the oligonucleotide pair, the tumor suppressor gene PTEN / MMAC1 that are highly conserved, it possible to amplify the homologues and their pseudogene that was found.
