Final answer:
Genes that are located close together on the same chromosome tend to be inherited together, violating the law of independent assortment.
Step-by-step explanation:
According to Mendel's law of independent assortment, genes sort independently of each other into gametes during meiosis. However, genes that are located close together on the same chromosome tend to be inherited together, violating the law of independent assortment. This is because recombination, or crossover, can occur between genes on the same chromosome, resulting in the exchange of genetic material. Genes that are located far apart on the same chromosome are more likely to assort independently because recombination events occurred in the intervening chromosomal space.
