Question

Which plant was used by Mendel to give the laws of inheritance?

  1. Bitter gourd

  2. Bottle gourd

  3. Garden peas

  4. Wild peas

Hint:

The plant has short germination period.

The correct answer is:

Garden peas


    • Gregor Mendel is the Father of Genetics
    • The scientific explanation for heredity was explained by him on the basis of his experiment with garden peas
    • 7 different phenotypes or physical appearances were discussed: seed shape, seed color, flower color, pod shape, pod color, flower position and stem length
    • A cross was made between two plants: dominant and recessive
    • The dominant and recessive plants showed contrasting phenotypes

    • The garden peas have a short germination period of 7 to 14 days
    • The basics of heredity was explained by Gregor Mendel
    • The traits exhibited by both dominant and recessive plants are as follows:
      CharacterDominantRecessive
      Seed shapeSmoothWrinkled
      Seed colorYellowGreen
      Flower colorPurpleWhite
      Pod shapeInflatedConstricted
