Gregor Mendel
1822-1884 Johann Gregor Mendel was an Austrian monk born in what is now the Czech Republic. Mendel is known as the father of genetics. He gave up science when he became an abbot. He contributed to genetics through his work with peas and realized the basic structure of knowledge of genetics: the fundamental laws of inheritance. He also realized that genes come in pairs that are inherited and that traits are defined by their gene pair. He has three laws: the Law of Segregation, the Law of Independent Assortment and the Law of Dominance. However, not all of his work was perfect or completely correct. Some of his theories only worked for peas, or only worked for very simple genes and traits.
The Law of Segregation
The Law of Segregation states that each inherited trait is defined by a gene pair. For example, a pea plant's genes for color could be GG, Gg, or gg.
The Law of Independent Assortment
The Law of Independent Assortment states that gene pairs are completely independent of each other. Inherited traits do not influence each other. For example, a pea plant's height does affect its color at all.
The Law of Dominance
An organism with alternate forms of a gene will express the form that is dominant.
