Genetics & Evolution is a core second year unit for BBiotechMedRes, BMarAntSc, and BSc students majoring in Plant Science or Genetics, and important for any student studying Biological Sciences. The unit offers an introduction to genetics and evolution, and integrates classical and molecular approaches to understand genetic control, genetic manipulation, and evolutionary processes. The unit starts with a review of classical genetics and develops the themes of linkage, recombination, cytogenetics, and quantitative genetics. We then move to a discussion of molecular genetics; including DNA analysis, forward and reverse genetics. This leads to an overview of biotechnologies, ranging from breeding and domestication to genetic modification. Evolutionary processes are illustrated with the dramatic radiation of the angiosperms, and population genetics with the equally dramatic radiation of the humans. The practical component of the unit is a mix of lab-based genetics experiments; technique development in cytology, artificial crossing and molecular genetics; and determination of evolutionary relationships.
