Final answer:
Linked genes tend to be inherited together and therefore do not follow the law of independent assortment, as they are located close together on the same chromosome.
Step-by-step explanation:
Linked genes generally do not follow the laws of independent assortment. This is because genes that are located physically close to each other on the same chromosome tend to be inherited together, which is known as linkage. Mendel's laws, including the law of independent assortment, are based on the idea that alleles sort into gametes without influencing each other's inheritance. However, linkage can disrupt this process, causing certain combinations of alleles to be inherited together more frequently than would be expected by chance.
In contrast, incomplete dominance refers to a scenario where the heterozygote displays an intermediate phenotype, and codominance occurs when both alleles are simultaneously expressed in the heterozygote. Pleiotropy describes the situation in which a single gene has multiple phenotypic effects.
