Law of Segregation: Allelic pairs separate or segregate during gamete formation and the paired condition is restored during fertilization.


Law of Independent Assortment: The plants with new combination are seen in F2 generation (Tall wrinkled) (Dwarf round) is only possible when the two gene pairs for height and seed shape (assort) independently of each other during gamete formation
