Genetics is a form of information science. Three levels of rules that govern the transmission of genetic information. From dna to gene action within and between cells. Over many generations within populations of organisms. Blending theory: a commonly held view in the 1800s in europe. It was the belief that inheritance worked like the mixing of the fluids such as paints. Also provided no mechanism by which the heredity fluids it imagined, once mixed, could be separated. The long-term expectation of blending theory over many generations of intermating among individuals is that all members of the population will come to express the same average value of a trait. Clearly this is not how nature works. Gregor mendel- a monk in the garden. Was working to understand the rules that govern the transmission of traits from parent to offspring after hybridization among different varieties of pea plants. He crossed a pea variety with purple flowers to one with white flowers.
