With a primary focus on eukaryotic organisms, this course deals with genetics at cellular and organismal levels, population genetics and microevolutionary processes. The genetics section deals with the structure and function of the DNA molecule and the flow of genetic information from genes to products, genome structure and organization, mitosis, meiosis and transmission genetics: inheritance of qualitative characters and linkage. The evolution section deals with population genetics: Hardy-Weinberg law, basic micro-evolutionary processes, quantitative genetics and speciation. Basic molecular evolution at whole genome level, and methods for studying genetic variation in natural populations are included in the course. The knowledge from theoretical aspects of the course will be consolidated and exemplified in problem solving exercises, group discussions and laboratory work. In addition, an individual specialization is made within a selected part of the course's subject area that connects to the central content of the syllabus for biology in upper secondary school. The course is very relevant and valuable for teachers in the coming working life.
