Mendelian Inheritance Using Seeds Of Different Colours/ Sizes Of Any Plant

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.
