Introduction to Evolutionary Quantitative Genetics

Course overview

The rate and direction of adaptive evolution critically depends on the additive genetic variances and covariances underlying the traits subject to selection. As a consequence, understanding the genetic basis of complex morphological, life-history, physiological, ornamental and behavioural traits is crucial if we are to understand their evolutionary potential, and the evolutionary process in general.

Quantitative genetics uses the phenotypic resemblance among related individuals to infer the role of genes and the environment in shaping phenotypic variation. Depending on the species, we can use data obtained from breeding experiments in captivity (e.g. insects), or from individual-based monitoring programs in the wild (e.g. birds and mammals). Especially the latter has benefited greatly from the application of animal model methodology, originally developed in animal breeding to identify individuals of high genetic merit. By simultaneously using the resemblance among all individuals in the pedigree, these methods provide more precise and accurate estimates of genetic and non-genetic variance components (heritabilities and genetic correlations). Furthermore, they allow for the estimation of individual-level genetic effects (breeding values), and thereby the inference of evolution.

In this course we will cover everything from basic quantitative genetic theory and statistics to advanced mixed model-based approaches. You will learn how to estimate genetic variances and covariances in wild and captive populations, and how to test for evolutionary change. Along the way, you will be exposed to the main software packages, and the R packages MCMCglmm and ASReml-R in particular, and you will learn about their strengths and weaknesses. You are strongly encouraged to bring your own data (if you have it), which you will be able to work on during the course and which will allow you to put the theory into practice.

You can check the list of Ambassador Institutions HERE. If you want your institution to become a Transmitting Science Ambassador please contact us at communication@transmittingscience.org.

Discounts (see Funding below) are not cumulative and apply only on the fee.

We offer the possibility of paying in two instalments (contact the course coordinators).


If you choose the Accommodation Package you will be hosted at Alexander Hotel in Gerakári village (take a look at the venue), in shared en-suite twin rooms, although you will only share rooms with other course participants. There is a possibility that the rooms will be mixed. If this is an inconvenience for you, and you would prefer to stay in an all-female or all-male room, please indicate so in the “Comments” field of the Registration form (below).

If you prefer to stay in a single en-suite room, you can do so with a supplementary charge.

The Accommodation Package includes transportation from the centre of Heraklion to the venue and back, at the start and end of the course, respectively. The trip takes around 1 hour 50 minutes each way. If you require transportation from or to Chania (the other city of Crete with an airport), please contact the course coordinator who can arrange it at an additional cost.

If you do not wish to take the Accommodation Package, you can find a few other options in the surrounding area. However, please be aware that access to and travelling around the area requires a private vehicle as public transport is scarce. Therefore, course participants will find choosing the Accommodation Package more convenient.
