The description that best explains Mendel's law of independent assortment is:
**The arrangement of each pair of homologous chromosomes on the metaphase plate during metaphase I is random with respect to the arrangements of other pairs.**
This statement reflects the principle that the orientation of each pair of homologous chromosomes is independent of the orientation of other pairs. As a result, the different combinations of chromosomes can lead to a variety of allele combinations in the gametes, demonstrating the independent assortment of alleles for different genes during meiosis.
