1. Mendel has given three laws of inheritance: (a) Law of Dominance (b) Law of Segregation and (c) Law of Independent Assortment.
2. When he crossed tall pea plants with dwarf pea plants, in F1 generation all offsprings were tall.
3. Then he self fertilised the individuals from F1 generation and as a result he found that 3 tall plants and one dwarf plant. from this he concluded that tallness is dominant over dwarfness and therefore hides its effect in F1 generation. But the two alleles though remained together for a long time, didnot blend or mix and therefore no intermediate height plant was there. That gamates containing different alleles of a character segregated.
4. Then he took two characters under consideration. Seed shape and seed color. Yellow seeds dominant over green seeds and round seeds dominant over wrinkled seeds.In F1 generation, all yellow and round seeds developed. When they were self fertilised, various combinations of seed shape and color came into existence in the ratio of 9:3:3:1.
5. Even yellow wrinkled and green round seeds occured which were different from parental and F1 generation. That though alleles of two different characters remained together but they were independent of each other and doesnot effect their inheritance. Hence, they are independently assorted.
