Genetics is the study of inheritance or how organisms use and transfer biological information during their lifetimes. An understanding of the principles of genetics is important for an informed awareness of many human problems related to genetic dysfunction. Furthermore, knowledge of genetics is necessary for students whose future professions involve the physiology, pathology, agricultural, food science, nutrition, microbiology and biotechnology fields.

The course presents the scientific basis of heredity. The course commences with a review of mitosis and meiosis, an overview of Mendelian genetics and introduces complex genetic traits and the effects of inbreeding. Next, the impacts of gene frequency changes on the evolution of populations are considered. Mapping the location of genes on chromosomes, chromosomal variation and the effects of mutations on gene expression are studied. Aspects of medical and agricultural genetics are explored in detail including the genetic basis of human, animal and plant disease, DNA testing, genetic counselling, biotechnology and gene therapy.
