| The main part (tronc commun) of the course is articulated on two main fields: quantitative and population genetics .
Population genetics seeks to explain the origin and the maintenance of genetic variability in the populations, and its importance and significance in terms of adaptation and evolution.
Quantitative genetics is the genetics of the characters with continuous variation (some exception) and with complex determinism, i.e. controlled by several genetic factors and several nongenetic factors.
The concepts learned in the main part are applied to the genetic selection of the animals for production (VETE0038-2) or to the animals
of sport and company (VETE0038-1)
The topics approached are:
- animal domestication
- Introduction to population genetics : law of Hardy Weinberg and extensions, evolutionary forces, co-evolution
- Introduction to quantitative genetics: decomposition of the phenotypical variation of the quantitative characters, estimate of the genetic parameters and the values of breeding, calculation of the genetic profit
- Strategies for genetic improvement of the domestic animals |

| The concepts learned in the main course (tronc commun) are applied to the genetic selection of production animals. |

| Course objective : |
| | common courses |
|
| At the end of the course, the student will be able of:
1. identifying when and how genes fluctuate in time, which forces make them vary and how these fluctuations may explain the mechanisms of evolution of the animal species (wild and domestic)
2. identifying data necessary to the genetic evaluation of sport and production animals, and understanding the mathematical models used in animal selection
3. to apply the concepts learned in the course to the selection domestic animals |

| Prerequisites : |
| | common courses |
|
| Knowledge necessary to the comprehension of this course is those desired of the students of third year in veterinary medicine (or the equivalent), i.e., to understand the basic concepts in genetics and statistics |
|
|
| Workshops : |
| | common courses |
|
| A handbook of exercises in relation to the theory is provided to the students |
|
|
| Organization : |
| | common courses |
|
| The course on population genetics is available at http://www.webct.ulg.ac.be. The students have access to the site freely. A partial examination is organized after the first four-monthly period.
The course on quantitative genetics and its applications in animal breeding are presented in weekly plenary sessions. An examination is organized at the end of the second four-monthly
period. |

| Assessment : |
| | common courses |
|
| At the end of the two parts of the course, the student will be able, individually, without the assistance of the notes:
- of solving with the necessary precision the exercises and problems referring to the course, with the assistance of a form and a calculator,
- of understanding the illustrations (diagram, appear, graph, table, ...) of the concepts learned during the course,
- of recognizing and identifying, without any help, important concepts
- of extrapolating learned oncepts to evolutionary phenomena observed in animal populations and to method of animal breeding |
