Difference between complete and incomplete linkage
Linkage:-The phenomenon of certain genes staying together during inheritance without separation due to their being present on the same chromosome is termed as linkage. It can be both complete and incomplete linkage.
Complete linkage- When the genes are tightly linked , resulting in very low percentage of recombination. In such condition, only parental or non cross over type of gametes are formed.
Incomplete linkage:-When the genes were loosely linked on a chromosome and show higher percentage of recombination. In such condition non parental type of gametes are formed.
