So we have one homologous chromosome and we have a second homologous chromosome. Now, within this Homologous chromosome pair, we have one of the chromosomes that carries the uppercase G. And the other chromosome within this Homologous pair carries the lowercase G. In this other Homologous pair, we have one of the chromosomes. Carries the uppercase t and the other chromosome carries the lowercase t. Now, the reason that we have the law of independent assortment in the first place is because of the process of meiosis that takes place when this individual, when the organism forms gametes, before fertilization actually takes place. So to see how that actually is, let's look at the meiosis process as it takes place within this particular organism. So before meiosis one can actually begin, this cell must undergo interface. And during the process of interface, we have replication taking place.
