serg [7]

The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

<h3 /><h3>What is a random mutation?</h3>

Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.

Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
