Linkage refers to the physical association of genes on the same chromosomes. The genes that show linkage are called linked genes. These linked genes show the same kind of inheritance pattern and are inherited together in the next generation. For example, a cross between yellow body and white eyes and wild type parent in a Drosophila will produce wild type and yellow-white progenies. It is because yellow bodied and white-eyed genes are linked. Therefore, they are inherited together in progenies. The percentage of parental types and recombinant types is 98.7% and 1.3% respectively.
