Question

What is the principle of linkage?

Answer 1

Linkage:

1. The physical association of genes on the same chromosome is called linkage.
2. The strength of linkage depends upon the distance between two genes.

Principle of linkage:

1. When two genes or more genes are linked together on the same chromosome the tendency to form recombinants is reduced.
2. The two or more genes are said to be linked when they are located on the same chromosome and cannot segregate independently as they are inherited together.
3. The linked genes are arranged in a linear fashion.
