Gregor Mendel — "I have been called a fool, but time will prove me right."

"The value and utility of any experiment are determined by the fitness of the material to the purpose for which it is used."

"The experiments described were begun in 1856. The plants were grown in the garden of the monastery."

"Thus, on the average, among four plants two have the hybrid trait Aa, one the parental trait A, and the other the parental trait a. Therefore, 2Aa+ A +a or A + 2Aa + a is the empirical simple series f…"

"You should regard the numerical expressions as being only empirical, because they can not be proved rational."

"The experiments lead to the conclusion that the characters of the two parental forms are transmitted to the hybrid unchanged."
