Heredity is the process of passing on characteristics from parents or ancestors to offspring. It is through this process that the daughter cell or organism acquires the characteristics of the developing cell or organism. The study of heredity in biology is called genetics. Charles Darwin, through his theory of evolution, illustrated the process of evolution and natural selection of organisms through hereditary variation to pass on their traits to their offspring. When he declared openly his development policy in 1859, he was unaware of the mechanisms by which he overcame the traditional traits. Later, in 1865, Gregor Mendel attempted to exemplify these mechanisms with some simple studies of pea plants in his garden. But their conclusions were not immediately accepted. Then in 1901 his findings were rediscovered and accepted. Gregor Mendel said that these genetic traits are passed on to the next generation under certain rules. Those laws were later called "Mendel's Laws". However, the findings of their study were considered to explain large differences such as qualitative differences.
