Quote by Wilhelm Johannsen

"Genetics is the science of heredity, and heredity is the fundamental principle of life."

"The gene is the unit of heredity, but it is not the unit of evolution."

"Nature does nothing suddenly, and gradualism is the law of change."

"Pure lines are the foundation of scientific breeding."

"Peace comes from a good conscience."

"Life is too short to hold grudges."

"A man's home is his sanctuary. It should be treated as such."

"The world is chaotic enough. At least your home should make sense."
