Gregor Johann Mendel

Gregor Mendel was one of the first people in the history of science to

discover genetics. He independently discovered his work and lived in Brunn,

Czechoslovakia. In Brunn he was a monk and later the Abbot of the church in

Brunn. While he was in Brunn he performed many experiments with garden

peas. With the information he observed he wrote a paper where he described

the patterns of inheritance in terms of seven pairs of contrasting traits that

appeared in different pea-plant varieties. All of the experiments he performed

utilized the pea-plant, which in this case is the basis of the experiment.

Mendels work was reported at a meeting of the Brunn Society for the Study of

Natural Science in 1865, and was published the following year. Mendels paper

presented a completely new and unique documented theory of inheritances,

but it did not lead immediately to a cataclysm of genetic research.

The scientists

who read his papers of complex theories, dismissed it because it could be

explained in such a simple model. He was rediscovered by Hugo de Vries in The

Netherlands, Carl Correns in Germany, and Evich Tschermak in Austria all at the

same time after 1900. They named the units Mendel described 'genes.' When

the gene has a slighty different base sequence it is called an 'allele.'

Mendel also developed 3 laws or principles. The first principle is called

the, 'Principle of Segregation.' This principle states that the traits of an

organism are determined by individual units of heredity called genes. Both adult

organisms have one allele from each parent, which gives both organisms 2

alleles. The alleles are separated or 'segregated' from each other with the

reproductive cell formation. Mendel's second principle is the,
