The subject Genetic Diversity and his applications to the study of the marine organisms contributes a wide vision on concepts and genetic tools of application for the management, conservation and study of species and marine populations. The questions treated in this subject include the study of the molecular technicians for the analysis of the genetic variation, the distribution of the intraspecific variability and his quantification, the molecular footprint of the adaptation, the study of the genic expression, and the variation in quantitative characters. The lessons *magistrales will be complemented with practical sessions in which the students will be able to exercise the knowledges purchased in the theoretical classes. As I complement to the face-to-face training, will make activities no face-to-face in which the students will put in practice the concepts learnt in the matter through the resolution of practical cases and the realisation of works *tutorizados by a professor, facilitating like this the personalised work and the integration of different sources of information.
