• A draft sequence of the chicken genome will be available by early 2004. This event conveniently marks the start of the second century of poultry genetics, coming 100 years after the use of the chicken to demonstrate Mendelian inheritance in animals by William Bateson. How will the second, post-genomic century of poultry genetics differ from the first? A whole genome shotgun (WGS) approach is being used to obtain the chicken sequence, with the goal of generating approximately six-fold coverage of the genome. Bacterial artificial chromosome (BAC) and fosmid clone end sequences, along with a BAC contig map integrated with genetic linkage and radiation hybrid maps, will form the platform for assembly of the WGS data. Rapid progress in global analysis of chicken gene expression patterns is also being made. Comparative genomics will link these new discoveries to the knowledge base for all other animal species. It’s hoped that the genome sequence will also provide common ground on which to unite studies of the chicken as a model species with those aimed at agriculturally-relevant applications. The current status of chicken genomics will be assessed with projections for its near and long term future.
