Solution
A linkage or genetic chromosome map is a linear graphic representation of the sequence and relative distance of the various things present in a chromosome. A chromosome app is also called a linkage map or the genetic map.
The per cent of crossing over between two genes is directly proportional to the distance. The unit of crossing over has been termed as centiMorgan.
