INHERITENCE....
Gregor Mendel-
Gregor Mendel was a monk who lived in Austria, he was born in 1822 and lived until 1884. He was often called the father of genetics. Mendel was born to a peasant family but went on to study at St. Thomas Monastery of Augustnitian Order and proudly in 1847 he became a priest. For a few years Mendel enjoyed this occupation but he realized that was not his life goal. Mendel strived to become a teacher and later attended the University of Vienna to study math and biology. Mendel studied hard but it was not enough his dream of becoming a teacher was shattered. Even though Mendel did not become a teacher he did not give up and he began to study genetics.
Mendel was very curious and decided to investigate the inheritance of traits amoung pea plants, he studied their height, flower and pod position, seed shape, seed color, pod shape, and pod color. This was indeed very interesting to Mendel and because of him we have been able to experiment alot more today. Mendel created an experiment in which he crossed a true-breeding for plants of regular height and a true-breeding for plants of short height. The first generation plants were all of regular height although the second generation had three regular height and one dwarf. Through this experiment Mendel decided that an organism has two factors one from each parent and the second factor could be hidden by the first. These were later called dominant and reccesive traits. Using his discoveries Mendel uncovered three laws. The first law says that the sex cells of a plant can have two different traits both not the same. The second law read that characteristics are inherited independently from another. And the last law states that each inherited trait is determined by a gene from each parent. Gregor Mendel was extremly important and his amazing discovery has been greatly benefited today.
