Gene Mapping: Then and Now

Model organisms have long been valuable resources for mapping the genes responsible for specific phenotypes. Today, with the help of entire genomic sequences, scientists are equipped with additional tools to help them map genes to chromosomes. How does this work? How has genome sequencing changed the landscape of gene mapping? How do we use model organisms, like zebrafish, to locate specific genes involved in human biology?
