Lecture 4: Genetic drift

Infinite population size is one of the HWE assumptions, but clearly it does not hold. However, for many large populations it can be good enough. In this lecture, we will consider what happens if the population is not very large. 3,833 more words

Lecture 3: Selection

Remember the assumptions of Hardy-Weinberg equilibrium (HWE)?

  • Infinite population
  • Random mating
  • Random survival and propagation
    • no natural selection
    • no genetic drift

This lecture explores what is happening to frequencies of genes and genotypes when we apply natural selection acting on one or more phenotypes in the population. 3,270 more words

Lecture 2: The mathematics of genes

Remember what is needed for natural selection to occur: reproduction, inheritance, variability and variable fitness. In the following lectures, we will delve into the field of population genetics, in which we study the effects of variability, natural selection and genetic drift on simple, abstract, model populations. 2,148 more words
