Solution and Explanation
Linkage: It is the physical association of two or more genes on the same chromosome, leading them to be inherited together.
Factors: 1. Distance: Linkage is inversely proportional to the distance between genes (closer genes = stronger linkage). 2. Crossing Over: Higher frequency of crossing over reduces the strength of linkage.
