In his study experiments, Mendel chose the backyard pea plant, scientifically known as Pisum sativum because it simply develops in huge figures and its subsequent creation can be re-used. Pea plants undergo self- and cross-pollination processes since they have masculine and feminine reproductive parts. Mendel chose traverse reproduction of the ordinary pea vegetation, and after his observations for numerous creations, he revealed that some characteristics occurred in the progeny with no combination of parental traits. In a case where the flowers are violet or colorless, the progeny of traverse-pollinated vegetation does not contain middle colors (Mendel, 1865).
Mendel highlighted seven characteristics that are simply predicted and actually appear in single or diverse forms. The forms ranged from flower and seed color; the form of the seed, the peapod’s color and form among others. It was noteworthy that the characteristics do not appear in progeny strands with middle shapes in contrary to the top thesis at that period, which stated that hereditary characteristics combined from age group to the other (Bateson, 1909). The foundation for his results, regarding the character of hereditary legacy, was pointed by the traverse pollination of thoroughbred strands with certain characteristics. In traverse pollination strands that fabricate golden or emerald pea kernels, the first progeny age group had golden seeds. The next production had a larger number of golden seeds compared to the emerald (Mendel, 1865).

Consequently, Mendel found out that the heritage of every characteristic is affirmed by unmovable elements, biologically known as genes, and that a single element from both parents is inherited. He also found out that a character may not appear in a person although it can be conceded to the following stage of production. Mendel also did a research in which the seed dye of the original strands was homozygous, in other words, it had two equal shapes, which were two golden and two emerald. The first production was heterozygous, meaning it had acquired two diverse forms from the original strand. It is understandable after the view at the inherent structure, known as genotype, rather than the visible traits, known as phenotype (Henig & Robin, 2000).
From Mendel’s examination on the seven qualities of the plant, a single shape was unaltered and would be preceded to the following stage of production. Mendel’s research study is reviewed in the theory of separation and sovereign variety. The process of separation takes place through gender unit development or meiosis, whereby a certain character goes from the original plant to the progeny. In the theory of sovereign variety, diverse forms are passed to progeny separately. There is no probability of present grouping of genes in any parent (Bateson, 1909). The two standards are the basics of present art of genetics.
