About the Cover

Gregor Johann Mendel 191st Birthday, (July 20, 1822 – January 6, 1884)
Father of Genetics
Gregor Mendel, known as the "father of modern genetics," was born on July 22, 1822 in Austria. He discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity. He conducted pea plant experiments between 1856 and 1863 and established many of the rules of heredity. Mendel had access to an experimental garden in which he could breed “true” lines of pea plants and patiently wait for them to crossbreed in specified combinations. He worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. Using the example of seed color, his results showed that when a yellow pea and a green pea were bred together their offspring plant was always yellow. However, in the next generation of plants, the green peas reappeared at a ratio of 1:3. To explain this phenomenon, Mendel coined the terms “recessive” and “dominant” in reference to certain traits.
