Independent assortment of genes does not take place when:
Genes are located on homologous chromosomes
Genes are linked and located on the same chromosome
Genes are located on non-homologous chromosome
All the above
, Mendel's Law of Independent Assortment holds true for genes situated on different chromosomes. However, Morgan's experiments revealed that when two genes in a dihybrid cross are situated on the same chromosome, they are physically associated or linked. These linked genes do not segregate independently of each other, leading to a deviation from the expected 9:3:3:1 ratio , , .
