Produced while McClintock was a National Research Council fellow at the University of Missouri, this paper resulted from observations she made after receiving correspondence from researchers at Berkeley on the existence of unusual variegations in some plants. McClintock argued that variegations must have resulted from sister-strand exchanges after ring chromosomes formed early in plant development.
