ST341 Statistical Genetics
Throughout the 202021 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and oncampus delivery through the year, and you should read the additional information linked on the right hand side of this page for details of how this will work for this module. The contact hours shown in the module information below are superseded by the additional information.You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.
All dates for assessments for Statistics modules, including coursework and examinations, can be found in the Statistics Assessment Handbook at http://go.warwick.ac.uk/STassessmenthandbook
ST34115 Statistical Genetics
Introductory description
The module runs in Term 2 and will introduce students to probabilistic models and statistical methods used in the analysis of genetic data.
This module is available for students on a course where it is a listed option and as an Unusual Option to students who have completed the prerequisite modules.
Prerequisites:
Statistics Students: ST218 Mathematical Statistics A AND ST219 Mathematical Statistics B
NonStatistics Students: ST220 Introduction to Mathematical Statistics
Module aims
Students will gain a basic understanding of the probabilistic models underlying the field of population genetics, and be exposed to practical applications of common statistical tests.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Discretetime reproductive models  WrightFisher, Moran. Coalescent limit. Properties of the standard coalescent, models of mutation, summary statistics and tests for neutrality, e.g. Tajima's D. HardyWeinberg laws, recombination, linkage mapping, linkage disequilibrium, association testing, an overview of genomewide association studies.
Learning outcomes
By the end of the module, students should be able to:
 Describe simple discretetime reproductive models and use them to derive the standard coalescent model
 Apply the predictions of coalescent theory to test for departures from neutrality, using simple datasets of DNA sequence variation
 Use simple datasets to evaluate the evidence for associations between genetic loci and Mendelian diseases
 Discuss the practical issues involved in scaling up association testing to whole genomes.
