Genome mapping It is based on the use of genetic techniques to construct maps showing the positions of genes.

Genetic mapping Is the creation of a genetic map assigning DNA fragments to chromosomes. Genomic DNA sequencing of the species has been completed. The fragments are identified by small tags. Markers

Ways of genome mapping There are two ways of genome mapping Genetic linkage mapping Physical mapping

Physical mapping In physical mapping, the DNA is cut by a restriction enzyme. Once cut, the DNA fragments are separated by electrophoresis. Get their physical map.
