Gregor Johann Mendel was a great scientist and he was known as the father of genetics or modern genetics. Mendel performed various types of cross-breeding experiments and then allow the offspring to self breed. His first paper " Experiment on plant Hybridisation" was published in the fourth volume of "Annual proceeding of natural history society" of Brunn in 1866. His work remained neglected for a about 34 years due to Limited circulation of proceeding, his finding was ahead of his time, lack of aggressiveness to his personality, the scientific world was being rocked by Darwin theory of evolution at that time and he failed to reproduction the results in Hawkweed. Later on, in 1900, his work was rediscovered by Hugo de Vries, Correns and Tschemark. Corren formulated his work in different laws.
