Gregor Mendel

Extracts from this document...

Introduction

Gregor Mendel Gregor Mendel was born on July 22nd, 1822 in Hyncice, Moravia which is now Czech Republic. He was born Johann Mendel into a poor farming family. His academic abilities were recognized by the local priest, who persuaded his parents to send him away to school at the age of 11. His grammar school studies completed in 1840, Mendel entered a two-year program in philosophy at the Philosophical Institute of the University of Olmütz (Olomouc, Czech Rep.), where he excelled in physics and mathematics, completing his studies in 1843. As his father’s only son, Mendel was expected to take over the small family farm, but he preferred a different solution to his predicament, choosing to enter the brünn monastery as a novitiate of the Augustinian order, where he was given the name Gregor. ...read more.

Middle

Once abbot, his administrative duties came to occupy the majority of his time. Mendel discovered the principle behind genetics by studying the inheritance of a single factor in pea plants. The inheritance of single characteristics is called monohybrid inheritance. He bred a pure breeding red pea plant with a pure breeding white pea plant and found that they always produced red flowers (the F1 generation). Mendel called the red characteristic dominant. Then when he bred two red pea plants together, he discovered that the next set of flowers were a mixture of red and white pea flowers (the F2 generation). The ratio of red to white was 3:1. Mendel called the white characteristic recessive. From his experiments Mendel concluded that the peas must carry a pair of factors for each feature. When the seeds where formed, they inherited one factor from each parent at random. ...read more.

Conclusion

The genes for each trait separate themselves during gamete production. Gregor Mendel is so important to modern day science as if it wasn?t for him conducting experiments and making conclusions we may never have discovered the laws of heredity on which the modern science of genetics relies upon. His work led to the discovery of inheritance, dominant and recessive traits, genotype and phenotype, and the concept of heterozygous and homozygous. Unfortunately, Gregor Mendel was not recognized for his work by his fellow scientists at the time he was alive. He found actual proof of the existence of genes, and is considered to be the father of genetics, though his work was relatively unappreciated until the early 1900's. His work was ignored by the larger scientific community partly because it wasn?t published in a widely read journal and partly because it tackled a problem in the physical basis of heredity that few other scientists were concerned about at that time. ...read more.

4 star(s)

****
A good overview of the life and career of Mendel which is well written and detailed. To get 5 stars more information on his study of inheritance in peas is needed.

    Mutations may arise due to environmental factors. For example a mutation can be caused by the breakage of one or both strands of DNA molecules.
