The International Congress of Genetics (ICG) is a five yearly conference for geneticists. The first ICG was held in 1898. Since 1973 It has been organized by the International Genetics Federation (IGF). The aim of the congress is to reflect on progress made in genetics, to celebrate the best of contemporary research and to anticipate future developments in the discipline. It is one of the most important genetics meetings, presenting all subfields of the discipline. These subfields cover all present-day experiments using the powerful genomic technologies. Also, the benefits and wider implications of genetic research to societies at large are explored. 10 plenary lectures and 42 parallel symposia covering basic and applied genetics in microbes, plants and animals. Poster sessions will provide opportunities for discussing results and ideas.
