Análisis estadístico en biología molecular: Uso y aplicación en poblaciones vegetales

When the researches in basic biological sciences propose, produce or introduce methods and techniques that describe the variability of natural or experimental populations, it is necessary to review, analyze and evaluate the statistical procedures available and adequate for these circumstances. Sometimes it is required to develop statistical techniques for the analysis and interpretation of the data originated in experiments involving biological innovations. In agronomic research, the molecular biology and similar disciplines have proposed the isoenzymes, RFLP'S and the RAPDS to evaluate the variability, composition and genetic structure of natural and domesticated populations. In this review, it is discussed and described the use of genetic distances, coefficients of similarity, dendograms and multidimensional scaling as statistical techniques in agronomic experiments which use isoenzymes RFLP'S and RAPDS as genetic markers.
