Pissum sativum in Mendelian Genetics
(Advantages of Pisum satiuvum in the Hybridization Experiments of Gregor Johan Mendel)
Gregor Johan Mendel, the Father of Genetics, used Pisum sativum (garden pea) as the study material for his hybridization experiments. He studied the inheritance pattern of seven pairs of contrasting characters in Pisum sativum for deriving his conclusions. A combination of luck, scientific aptitude, foresight, mathematical background and most importantly the selection of suitable plant material (i.e., Pisum sativum) for the studies contributed the success of Mendel’s hybridization experiments.
Pisum sativum possesses many advantages as a study material in the hybridization experiment that knowingly or unknowingly helped Mendel to derive a logical conclusion from his crossing experiments. The advantages of Pisum sativum as a study material in hybridization experiments are given below:
Ø Pisum sativum is an annual plant with a short span of life cycle. Thus many generations can be produced within a short period of time.
