Positional cloning
Cloning a gene based simply on knowing its position in the genome without any idea of the function of that gene. Because this is the reverse of how things have been traditionally done, it has also been called reverse genetics.

DNA cloning of a sequence based on its map position, without knowledge of the gene product produced; used to identify disease-causing genes.
