A genetic linkage map for the zebrafish.

To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers were developed that quickly mapped lethal and visible mutations and that placed cloned genes on the map. This map is useful for the position-based cloning of mutant genes, the characterization of chromosome rearrangements, and the investigation of evolution in vertebrate genomes.

Identification of RAPD primers that reveal extensive polymorphisms between laboratory strains of zebrafish.

The zebrafish has recently emerged as a useful system for understanding vertebrate developmental genetics, despite the lack of a linkage map. To identify DNA-based genetic polymorphisms for constructing a genetic map, we have screened a collection of RAPD primers for their utility in identifying genetic polymorphisms between two laboratory strains of zebrafish. Here, we report 116 primers that identify 721 strain-specific genetic markers and show how they can be used in haploid genetics of zebrafish.
