☆Actually welcome to the concept of the Heridity and Evolution......
Basically linkage deals with the characteristics of F1,F2,F2 generation having close realtion in them .....

☆When two or more characters of parents are transmitted to the offsprings of few generations such as F1, F2, F3 etc. without any recombination, they are called as the linked characters and the phenomenon is called as linkage.

☆This is a deviation from the Mendelian principle of independent assortment.

☆Mendel’s law of independent assortment is applicable to the genes that are situated in separate chromosomes. When genes for different characters are located in the same chromosome, they are tied to one another and are said to be linked.
