The following segment of the course is taught by a member of te Department of Genetics

Dr Aylwyn Scally : Probability, Genome Sequencing and Population Genetics

These lectures introduce fundamental concepts of probability and randomness, and how to build probabilistic models of biological systems. Such models are essential and widely used tools for understanding complex biological phenomena, and are particularly important in genetics and genome sequence analysis. The lectures also introduce basic population genetics and the Hardy-Weinberg equilibrium as an important example of a probabilistic model.
