Throughout the course, we intend to give enlightenment regarding the practical side of detecting genetic differences between human populations therefore students may familiarize themselves with the conceptual background and medical aspects of the population genetics. The course also intends to show the relation between different disease spectrums and populations by international studies focusing on the detection of rare diseases, origin related researches, migration patterns and forensic medicine.
