The relatively short growth period is another advantage, meaning there was not a long wait for the results. Over eight years, Mendel studied pea traits one at a time and crossbred variants to systematically record how traits were passed on from one generation to the next: a mammoth task that involved approximately 28, pea plants. He also identified a consistent mathematical formula that explained the frequency with which each trait appeared and observed dominant and recessive traits.

Nineteenth century Austrian painter Gustav Klimt is known for the highly decorative style of his works, his most famous being The Kiss and the Portrait of Adele Bloch-Bauer. Chemist John Dalton is credited with pioneering modern atomic theory. He was also the first to study color blindness.
Francis Galton was an English explorer and anthropologist best known for his research in eugenics and human intelligence. He was the first to study the effects of human selective mating. French physicist Pierre Curie was one of the founding fathers of modern physics and is best known for being a pioneer in radioactive studies.
Sigmund Freud was an Austrian neurologist best known for developing the theories and techniques of psychoanalysis. Galileo was an Italian scientist and scholar whose inventions included the telescope. His discoveries laid the foundation for modern physics and astronomy. Gregor Mendel discovered the basic principles of heredity through experiments with pea plants, long before the discovery of DNA and genes.
He studied natural sciences and mathematics at the University of Vienna, Austria, but twice failed to obtain a teaching certificate, instead becoming a part-time assistant teacher and carrying out research in plant breeding. His most famous experiments were done between and , during which time he grew some 10, pea plants.
Pea plants are hermaphroditic, meaning they have both male and female sex cells and usually fertilise themselves. Mendel was able to cross-breed the plants by transferring pollen with a paintbrush.
Individual 14 a female is not affected with WS and mates with a male that is also not affected with WS. The couple has two female offspring, both of whom are not affected with the disease. Figure 3.
