Thus, a purple flower in the axial position is a doubly dominant trait in pea plants, and a white flower in the terminal position is a doubly recessive trait. They may represent the same (homologous, e.g., TT in case of pure tall pea plants) or alternate expression (heterozygous, e.g., Tt in case of hybrid tall pea plants) of the same character. The characters which always appear in two opposing conditions are called contrasting characters. He proposed that heredity is controlled by factors, which are now believed to be segments of chromosomes or genes. A cross was carried out between two pea plants showing the contrasting traits of height of the plant. The result of the cross showed 50% of parental characters. 1.
