The fish that has become a model organism for the genetic study of vertebrate development. The fish has a 3-month life cycle and produces large, transparent embryos. Large-scale mutagenesis experiments have generated a wealth of mutations that produce a dazzling array of abnormal phenotypes. The genome contains about 1,700 mbp of DNA distributed among 25 chromosomes.
