Genetic linkage is a process in which the genes present on the chromosome are located so close to each other that they cannot be separated and hence are transferred as a unit. It was studied by scientists back in 1905 that in pea plant, the genes responsible for the color of a flower and the shape of pollen grain are located very close to each other on the same chromosome and they are inherited together.
On the contrary, the genes that are located at a distance from each other tend to get separated through the phenomenon of genetic recombination which takes place during meiosis.
