Solution
Mendel’s Law of independent assortment holds good for genes situated on the homologous chromosomes.
Explanation:
Mendel’s law of independent assortment states that genes for different traits can segregate independently during the formation of gametes. This law holds true only for genes situated on different (non-homologous) chromosomes because such genes assort independently during meiosis. Genes located on the same chromosome tend to be inherited together (linked) unless crossing over occurs between them. Hence, independent assortment applies primarily to genes on non-homologous chromosomes, not on the same chromosome or homologous chromosomes carrying alleles of the same gene.
