Final answer:
Linked genes generally do not follow the laws of independent assortment because they are located in proximity on the same chromosome, but recombination can sometimes allow them to behave as if they are unlinked.
Step-by-step explanation:
Linked genes generally do not follow the laws of independent assortment. This is because linked genes are located physically close to each other on the same chromosome, meaning they tend to be inherited together as a pair. Despite this linkage, through the process of recombination, or "crossover," it is sometimes possible for these genes to be inherited independently if they are far enough apart on the chromosome for a crossover to occur between them.
The other options provided in the question, such as codominance and incomplete dominance, refer to how alleles express themselves in the phenotype of an organism, rather than how they inherit through generations. Pleiotropy occurs when one gene influences multiple phenotypic traits, and is not directly related to the concept of linked genes and their inheritance.
