The pig genome Web page provides materials for swine researchers, students, producers, and members of the industry with information covering all aspects of swine genetics, genomics, and animal breeding. This Web site is the home of a great deal of diverse and interesting information, including the pig genome database (PigBase) and the pig expressed sequence tag (EST) database, and it houses an animal gene mapping discussion forum (ANGENMAP mail list). This site also includes a bimonthly swine genome newsletter and information on gene mapping materials and information. This resource plays an important role in swine genetics and swine breeding education by including tutorial materials and lecture notes on genetics, gene mapping, QTL detection, and genetic linkage analysis. Many additional pig genome Web sites worldwide also can be accessed from this site.
