The number of linkage group is equal to … NettetAlthough linkage is an exception to this law as two genes are situated on the same chromosome, the case changes when there is a crossing over of chromosomes. Two different genes situated close together on the same chromosome tend to be inherited together. This phenomenon is called linkage. denise matthey
