Since the gene responsible for the color of pea and shape of seed of pea are not on different chromosome, yet Mendel acheives the sucess on explaining the segregation of the two different gene whether they are present on same chromosome or they present on different chromosome. When Mendel crossed the yellow coloured round seed plant with the green coloured wrinkled plant the result is only yellow coloured round seed plant. Although when Mendel crossed the yellow coloured wrinkled seed plant with the green coloured round seed plant, the result was same i.e. yellow coloured round seed plant. It means that the gene responsible for the yellow colour and round shape does not blend with each other i.e. does not mix with each other. They segregate during fertilization if still they present on same chromosome or on different chromosome.
