5. From 1840 to 1843, he studied practical and theoretical philosophy and physics at Philosophical Institute of the University of Olomouc.

6. He also struggled financially to pay for his studies. He become a friar in part because it enable him to obtain on education without having to pay for it himself. As the son of struggling farmer, the Monastic life in his word, spared him the “Perpetual anxiety about a means of livehoods .” Life of struggle

7. He was given a name Gregor when he Joined the Augustinian Friar . In 1843 he was admitted as a novice at the Augustinian Monastery at Brunn . He took an examination for a teaching certificate in natural science and failed in 1850. To remedy this he spent four term between 1851 to 1853, at the University of Vienna, where he studied Physics, Chemistry, Mathematics, Zoology, Entomology, Botany and Palaeontology. In first term he work in experimental Physics under the famous Physicist Christian Doppler. In 1853 Mendel as a teacher of Physics. MENDEL LIFE CONTINUE

8. In 1856 he took the exam to become a certificate teacher and again failed the oral part. In 1867, He replaced Napp as a abbot of the monastery. In 1868 his scientific work largely ended. Mendel died on 6 January 1884, at the age of 61, in Brno, Moravia, Austria from Chronic nephritis. After his death succeeding abbot burned all papers in Mendel collection to mark an end to the disputes over taxation. MENDEL LIFE CONTINUE

9. In 1856 he began his famous hybridization experiment on garden pea plant. In 8 February 1865 and 8 March 1865 he presented his work in a paper entitled “ Versuche uber pflanzenhybriden ” (Experiment on plant hybridization) at two meeting of Natural Society of Brno. Mendel papers was published in 1866 in “ Verhandlungen des naturforschenden vereines ” (Annual proceeding of natural history Society) in Brunn . But Mendel Research ignored by many Scientist community. ABOUT MENDEL EXPERIMENT

10. Its having three reason Disappointment of Nageli . Darwin research publication on “ Natural Selection ” in 1856. Mendel published his research paper on not well known publication because Mendel have no money to published his research paper on well known publication. REASON OF MENDEL IGNORANCE

11. In 1900 his findings were rediscovered by three scientist Hugo De vries from Holland, Karl Correns from Germany and Erich Tschermark from Austria independently. De Vries found Mendel’s research paper and he got it published in “Flora” in 1901. Correns postulates three law that are known as Mendel’s law of inheritance. REDISCOVERY OF MENDEL

12. The pea plant which Mendel chose for conducting experiments, is most ideal for controlled breeding, since it can easily be subjected to cross pollination. He identified very clear contrasting characters in the pea plants. He maintained an accurate record of all the observations he made on the breeding experiments that he had designed. He pooled the data obtained from similar experiments for different characteristics and analysed the results by using statistical methods and applying the law of probability. Recognize mistake’s of previous workers. REASON OF MENDEL SUCCESS.
