Abstract: The invention relates in general to the analysis of genetic markers in individuals of non-human origin, in particular the genotyping of outbred populations of rodents or fish. The invention relates specifically to the simultaneous amplification of at least five different polymorphic autosomal markers and at least one polymorphic Y-chromosomal marker of the mouse in a reaction preparation by means of polymerase chain reaction or other multiplex methods and the detection of the specific alleles for each marker of the multiplex method. The invention further relates to a kit for genetically identifying and/or for differentiating two or more animals from DNA extracts of individuals from wild-type populations, from different inbred or outbred strains, of an identical inbred or outbred strain, or from substrains of an identical inbred or outbred strain, in particular of the rat or mouse.

Abstract: Genetic characterisation of closely related inbreds is at present only possible by means of whole genome sequencing. This is however a time-consuming process. The invention addresses the need for a method to differentiate between closely related substrains of inbreds. The method involves analysis of at least two tandem repeat loci per chromosome. Said tandem repeat loci are characterised by high mutation rates. The amplified fragments are subsequently used to determine the alleles that are present at each amplified locus within the DNA sample.
