MT4530 POPULATION GENETICSAimsTo show how the frequencies of characteristics in large natural populations can be explained using mathematical models and how statistical techniques may be used to investigate model validity.
ObjectivesFor the topics given in the syllabus given below, students should, by the end of the course, have a general understanding of the biological systems at work and be familiar with the probabilistic models for them. They should also be able to apply the statistical techniques given in the course for testing model validity.Syllabus Basic concepts: genotypes and phenotypes, homozygotes and heterozygotes, dominant and recessive genotypes. Mendel's First and Second Laws, segregation ratios, goodnessoffit tests.  Random mating and random union of gametes.  HardyWeinberg Equilibrium: single diallelic locus case with and without dominance, estimation of gene frequencies, testing the fit, three allele case.  Inbreeding: self fertilisation, the coefficient of inbreeding, populations mixing selfing and random mating, general condition for equilibrium  Assortative mating  positive (PAM) and negative (NAM), incomplete dominance case, total and partial PAM under complete dominance.  Selection: changes in gene frequency and mean fitness, equilibria, time taken to effect changes.  Xlinked loci  basic properties, behaviour of gene and genotype frequencies.  Mutation: fate of a single mutation, oneway and twoway mutations, combined effects of selection and mutation.  Linkage: linkage equilibrium, estimating the strength of linkage.
 Genetic drift: WrightFisher model, effective population size, coalescence and gene genealogies.
