THE WORK OF GREGOR MENDEL

Gregor Johann Mendel was born on July 22, 1822 to peasant parents in a small agrarian town in Czechoslovakia. During his childhood he worked as a gardener, and as a young man attended the Olmutz Philosophical Institute. In 1843 he entered an Augustinian monastery in Brunn, Czechoslovakia. Soon afterwards, his natural interest in science and specifically hereditary science led him to start experiments with the pea plant. Mendel's attraction to research was based on his love of nature. He was not only interested in plants, but also in meteorology and theories of evolution. Mendel often wondered how plants obtained atypical characteristics. On one of his frequent walks around the monastery, he found an atypical variety of an ornamental plant. He took it and planted it next to the typical variety. He grew their progeny side by side to see if there would be any approximation of the traits passed on to the next generation. This experiment was "designed to support or to illustrate Lamarck's views concerning the influence of environment upon plants." He found that the plants' respective offspring retained the essential traits of the parents, and therefore were not influenced by the environment. This simple test gave birth to the idea of heredity. Overshadowing the creative brilliance of Mendel's work is the fact that it was virtually ignored for 34 years. Only after the dramatic rediscovery of Mendel’s work in 1900 (16 years after Mendel's death) was he rightfully recognized as the founder of genetics. WHY GREGOR MENDEL USED PEAS.

The reasons for Gregor Mendel to use pea plants in his experiment was, he needed plants that produced flowers that would be easy to protect against foreign pollen.  The special shape of the flower of the Leguminosae family, with their enclosed styles, drew his attention.  On trying several from this family, he finally selected the garden pea plant (Pisum sativum) as being most ideal for his needs.  Mendel also...
