Gene hunters and others who carry out linkage or association studies now have a powerful new tool in the form of a human genetic map with about five times the resolution of previous maps. Because individual variation in levels of meiotic recombination may limit the precision of genetic distances that can be obtained by genotyping polymorphisms in families, new strategies for building genetic maps of very high resolution will be required.
