In his 1970 book, Susumu Ohno stressed the importance of gene duplication in the evolution of the vertebrate genome and body plan. He elaborated the idea that duplication events provide novel genetic material on which evolution may act. Data are accumulating to show that extensive duplication events, perhaps incorporating the duplication of entire genomes, occurred in the lineage leading to teleost fishes. These duplications may have been pivotal in the explosive radiation of this highly successful vertebrate group. Thus, the teleosts provide us with an ideal opportunity to investigate the fates and functions of duplicated genes. A convenient system for these studies is the zebrafish, Danio rerio, which has become a popular genetic and embryological model.
