Question

Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though the animals were genetically identical and shared the same mother, they showed variations in their phenotypes that were beyond the normal range in expression.
Based upon today’s knowledge of genetics, which explanation describes the most likely cause of the phenotypic variations?

Answer 1

Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.

Mutation

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.
