Detailed explanation-1: -Although linkage is an exception to this law as two genes are situated on the same chromosome, the case changes when there is a crossing over of chromosomes. Two different genes situated close together on the same chromosome tend to be inherited together. This phenomenon is called linkage.

Detailed explanation-2: -Law of co-dominance, Law of incomplete dominance, and Pleiotropy.

Detailed explanation-3: -Mendel’s law of independent assortment does not apply to linkage. Inherited genes are said to be independent of one another under the law. Since two genes are located on the same chromosome, the linkage is an exception to this rule. Thus the independent assortment is violated by linkage.

Detailed explanation-4: -Genetic linkage is a violation of the Mendelian principle of independent assortment.

Detailed explanation-5: -This phenomenon is called genetic linkage. When genes are linked, genetic crosses involving those genes will lead to ratios of gametes (egg and sperm) and offspring types that are not what we’d predict from Mendel’s law of independent assortment.
