Testing the Hypothesis of Independent Assortment The theory of independent assortment was introduced to genetics by Gregory Mendel while studying heredity in pea plant (Pisum sativum). The principle gives an explanation of how various genes in an organism separates independently after the development of reproductive cells. Independent assortment is based on monohybrid cross, which is a type of breeding that encompasses parental generation with different alleles at the locus of interest. The testing of Mendel’s theory of independent assortment is carried out on a pea plant, the basic plant used by Mendel. The growing and crossing of the plant should be handled with care to prevent the occurrence of errors that may affect the realization of the desired results. A large pea plant farm is required while conducting the study, which should grow and mature in one season. The plants must be true breeding plants with a pair of traits each: dwarf plants with constricted pods and tall plants with inflated pods. It is important to note that the traits will be sorted independently; thus, resulting in a ratio of 3:1 for the 1st progeny and 9:3:3:1 for the subsequent progeny. Two pure breeds’ parental pea plants were crossed, which resulted in tall F1 offspring with inflated pods. The results indicated that the traits for tallness and inflated pods are dominant over the dwarf and constricted pods, which are recessive. The genes for tall and dwarf plants were represented by T and t respectively while those of inflated and constricted bonds were I and i respectively. All the F1 generation had the genotype of TtIi. The phenotypic ratio of the F2 generation is 9:3:3:1 for
