Abstract: A genomic analysis process is disclosed, in particular for analysing and localising hereditary properties in the genome. This process has applications in a large number of fields, in particular in medicine, agriculture, forensic medicine and fundamental research. This genomic analysis process is characterised in that the amplification products of microsatellites form genomic DNA samples are immobilised. The genomic DNA samples are separated on defined positions of the matrix, before or after being amplified into individual microsatellite markers, the individual positions are evaporated in a mass spectrometer and their molecular weight is determined.
