Document Summary
Laid foundation of the science of genetics by discovering principles of transmission of hereditary traits from generations to generations. In 1854, he began a series of cross- breeding experiments with the garden pea to learn about the mechanisms of heredity. Mankind knew by this time that they was some sort of hereditary nature of traits. Set up to do systematic series of cross-breeding experiments with the garden pea. Mendel used crosses of true-breeding varieties homozygous for the gene(s) controlling the traits. The traits that he studied had 2 forms (= 2 phenotypes) and they happen to have a simple genetic basis. Used true breeding variety (if you propagate this breed all the offsprings look like the parents - thy don"t change) of peas - looked at 7 traits (had only. 2 phenotypes) and they all happened to have simple genetic basis - excellent model species cross breeding - know definition. Monohybrid crosses - mendel"s first law (principle of segregation)
