The hypothesis that was being tested by Lederberg. Introduction: The variations caused in the genetic material of an organism from a source or randomly are called “ mutations .” The randomness in the mutation rate was shown by Lederberg in “replica plate experiment.” The minute changes in the “DNA fragment” caused the very new variations among the individuals which makes them different from each other.
