Question
Which plant was used by Mendel to give the laws of inheritance?
Bitter gourd
Bottle gourd
Garden peas
Wild peas
Bitter gourd
Bottle gourd
Garden peas
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:
Character Dominant Recessive Seed shape Smooth Wrinkled Seed color Yellow Green Flower color Purple White Pod shape Inflated Constricted Pod color Green Yellow Flower position Axial Terminal Stem length Tall Dwarf
