Methods and processes for conducting genetic analysis through protein polymorphisms, including identification of individuals, establishment of paternity and measurement of genetic diversity and distance. Some illustrative embodiments of methods of the present invention include the identification of peptide biomarkers using proteomic techniques, including liquid chromatography-tandem mass spectrometry from biological samples, using hair, dentin, or bone as a source of the protein to be analyzed. Other illustrative embodiments include the determination of allelic frequency and feasibility of protein polymorphism peptide biomarkers, and the application of these frequencies to allow statistical analysis and population genetics to be applied to collected biological samples.
