So this is the biological reason, the biological basis for the existence of the law of independent assortment as was devised, as was described by Gregor Mendel following his experiments with p plants. So if this takes place, these will separate to produce this cell. And this will be an arrangement of these chromosomes during metaphase two of meiosis. And now these will segregate as well. So these will go to one, these will go to another one producing upper case G, lower case T and these will go to separate sides producing lowercase G, uppercase T. So these are the possibilities the genotypes for the gametes that are formed for this particular heterozygous p plan so we have four different types of genotypes. So we have uppercase G, uppercase T, this possibility.
