Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.
<h3>Mutation</h3>
This refers to a sudden change to the DNA sequence of living organisms.
When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.
For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.
In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.

Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
<h3>What do you mean by Physical changes?</h3>
Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density.
Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter.
Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
