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."

"When life gives you lemons, make something beautiful."

"Creativity knows no bounds."

"Creativity is the expression of the soul."

"I'm making this up as I go."
