The present invention provides a method for detecting mutations in the genome of an individual, comprising amplifying at least one fragment from the genome for testing; linking a label unique to the individual to the DNA fragment(s); providing a reference fragment(s) provided with another unique label and corresponding with the fragment(s) for testing; mixing the fragment(s) and the reference fragment(s); subsequently separating the mixture by means of electrophoresis; making visible the unique label; and comparing the label pattern of the fragment(s) for testing with the label pattern of the reference fragment(s). It becomes possible with the method according to the invention to simultaneously test DNA samples of a number of individuals for mutations.
