Aim
To study the Mendelian inheritance using seeds of different colours/sizes of any plant.
Necessary Materials & Apparatus
- Petri Dish
- Enamel Tray
- Pea Seed Samples
Procedure
- Place 100 pea seeds in an enamel tray
- Separate the seeds into round and wrinkled and place them in two separate Petri dishes
- Note down the number of round and wrinkled seeds. Also, calculate their ratio.
- Repeat the procedure mentioned above for other contrasting traits such as the colour of the seeds.
Observation
- Create a table showing the characteristics of the seed along with the total number observed, number of seeds with contrasting characters and the ratio.
| (Example) | Serial Number | Characteristics | Total number of seeds | Seeds showing contrasting characters | Ratio |
| 1 | Shape of the seed | xxx | (X) round seeds; (Y) wrinkled seeds | X: Y | |
| 2 | Colour of the seed | xxx | (X) green seeds; (Y) yellow seeds | X: Y |
