Educational objectives
The main objective of this course is to provide knowledge of chromosome organization and the role and function of chromosomes in the process of heredity. The students should demonstrate to understand interconnections between chromosomes and evolutionary processes. Furthermore the knowledge of the main advanced technologies on cytogenetics.
Prerequisites
In order to be able to understand the subjects treated during the course the student is required to have basic knowledge on Botany and Genetics. Is also useful for the student to know the use of the main tools of a cyogentetic laboratory such as microscope and stereomicroscope.
Teaching methods
Theoretical lessons and practical training.
Other information
Knowledge of English.
Learning verification modality
The oral test consists on an interview of 30-40 min. Great importance will be given to the ability of the student to treat scientific topics using appropriate language.
Extended program
Relationships between biodiversity and evolution. Earth is home to a tremendous diversity. Distribution of biodiversity on the face of the earth: biosphere, biome, ecosystem, biocenosis, biotope, habitat. the need to order the living forms. different concepts of species. Cytogenetics for understanding biodiversity and evolution. The role of Cytogenetics for evolutionary studies. The genome structure. C-value and genome size. Type of DNA repeats. Satellite DNA. Structure and function of the eukaryotic chromosome. Banding techniques. The role of meiotic mutants in plant evolution. Numerical variants of chromosomes. Polyploidy and dysploidy. Application of in situ hybridization techniques: FISH and GISH. The molecular cytogenetics for the study of biodiversity, phylogeny and evolution. The origins of the agriculture. Plant and animal domestication. The concept of Vavilov of centres of origin of cultivated plants. . Agrobiodiversity.











Practicals will be held in the laboratory of Cytogenetics. Practicals will consist also in the study of scientific articles.
