Inbred Strains with Individuals of a Relatively Homogeneous or Constant

question 1

Essay

Inbred strains with individuals of a relatively homogeneous or constant genetic
background are often used to determine the influence of genes or the environment on phenotypic variation. Variation observed between different inbred strains reared in a constant or homogeneous environment would likely be caused by genetic factors.
What would be the source of variation observed among members of the same inbred strain reared under varying environmental conditions?
