Respuesta :

Linkage occurs when on the same chromosome, two genes are closer to each other . On the other hand, Crossing Over takes place when on the same chromosome, two genes are located far apart. Crossing Over may disturb the gene groups made by Linkage.

What is a linkage?

Linkage is the propensity of inheriting genes together on the same chromosome. It is a process in which genes are kept within a chromosome, so that it can be inherited together.

What is a crossing over?

Crossing over is a process of segregation of genes on the chromosome. It further sub-divides the chromosome into its component gametes.

Both, the process of linkage and crossing over are somewhat related to each other, but are yet different phenomenon. Genes are segregated into gametes through the process of crossing over. The lesser the distance in the same chromosome, the lesser is the chance of them being segregated through crossing over.
