Gregor Mendel’s Experiments and the Inheritance of Characteristics
How and When Mendel carried out his experiments: a. Briefly outline Mendel’s biography • Gregor Mendel (1822-1884) was an Augustinian monk of Austrian origin and is known as the Father of Genetics. • 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. • Mendel's attraction for scientific research was based on his love of nature in general. He was not only interested in plants, but also in meteorology and theories of evolution. • He also worked as a teacher and an investigator while living in the monastery in Brunn.
b. Describe the experiments carried out by Mendel and include any significant data • Mendel experimented with garden pea plants, investigating their breeding patterns to determine the inheritance of characteristics. • The traits he studies were: o Stem length: tall or short o The colour of the seed contents: yellow or green o The colour of the seed coat: grey or white o The shape of the seed: round or wrinkled peas o The colour of the unripe pod: yellow or grebe o Flower position: axial or terminal o Pod shape: inflated or constricted (see figure 1) • Over a period of 2 years, Mendel established pure-breeding lines of pea plants which he then cross-bred to study the inheritance of their characteristics.
