For that purpose several concepts and mathematical tools are selected towards establishing a quantitative method without a priori distorting the alphabet represented by the sequence of DNA bases. The synergies of associating Gray code, histogram characterization and multidimensional scaling visualization lead to a collection of plots with a categorical representation of species and chromosomes.engDoenças GenéticasDNAChromossomePhylogeneticsCorrelationVisualisationMultidimensional Scalingjournal article
