This course will provide a basic knowledge of genetic principles and their underlying mechanisms at the molecular- , cellular-, organism- and population-levels. The course deals with the structure, function and organization of genetic material in eukaryotes as well as differences compared to prokaryotes. Methods for determining the relative positions of genes in the genome is explained and different patterns of inheritance of hereditary characteristics are described. The main areas are transmission genetics, gene and genome structure, stability and variability, molecular methods, bioinformatics, genetic model systems, genetic control of life processes and factors and processes affecting the genetic composition in a population. The course also aims to make students familiar with the study, presention and discussion of original papers.
