This invention provides a method for processing information that allows the discovery of a correlation between predetermined individual-related information and nucleotide sequence-related information concerning an individual. This method comprises: step (a) of calculating a percentage for each piece of nucleotide sequence-related information using a first occurrence frequency and a second occurrence frequency, wherein the first occurrence frequency is calculated for each possible piece of nucleotide sequence-related information in a given position in a nucleotide sequence based on a predetermined population and the second occurrence frequency is calculated for each possible piece of nucleotide sequence-related information in the aforementioned position based on the population gathered for predetermined individual-related information concerning an individual; and step (b) of associating the percentage calculated in step (a) with positional information representing the aforementioned position and with the nucleotide sequence-related information for each the predetermined piece of individual-related information.
