Summary: The course introduces statistical methods in genetic relatedness and pedigree analysis, with applications in linkage analysis, relatedness inference and forensic genetics.


The study of genetic relatedness and how genetic information flows in families, is central in a variety of important research fields, including medical genetics, forensics and animal breeding. The aim of this course is to introduce the students to the elegant concepts and results forming the theoretical foundation of genetic relatedness, and to present in some detail several modern applications. In the exercises we will use R and the ped suite of packages for pedigree analysis.


Learning outcome:

After completing the course the student should have knowledge about:
* classical concepts and methods of statistical genetics
* important applications of pedigrees and relatedness, including forensic genetics and linkage analysis in medical genetics
* software for visualising and analysing pedigree data



Basic knowledge of genetics and probability.

All participants should bring a laptop with the R software installed (available from
