I had to investigate the effect of the mutation on the plants and then determine the type of inheritance pattern shown in each case. By following in the footsteps of the Father of Genetics ‘Gregor Johann Mendel’; I’ve attempted to achieve recreating (on a much smaller scale) one of his inheritance experiments conducted in 1856-1863. This particular experiment led him to create the Law of Segregation and the Law of Independent Assortment, which later became known as Mendel's Laws of Inheritance. By following the “Second Law” created by Mendel (Independent Assortment) it was possible to hypothesise that the growth rate of both peas and barley were manipulated by the phenotype and genotype of each individual plant, chlorophyll absorption within each plant and how had the inheritance pattern affected the overall biological mass/growth rate of the collective. Essentially the phenotype ‘Green’ has a higher probability to grow into adulthood without complication due to the Chlorophyll’s ability to absorb more light (to photosynthesise and grow) as opposed to the white or yellow phenotypes which absorb less light due to the colour pigmentation within their leaves. The inheritance pattern of both peas and barely contributes to the genotypes and phenotypes present within the plants. Theoretically had all barley and pea plants of a ‘Green Phenotype’ and the ‘GxG Genotype’ (G: Green) been bred as a species, all of
