Answer:
Variation observed between different inbred strains reared in a constant or homogeneous environment are often times caused by genetic factors, while variation observed among members of the same inbred strain reared under varying environmental conditions would likely be caused by nongenetic factors.
These Non-genetic factors transfers the parental phenotype or environmental components that causes variation in gene expression during offspring development.
Examples of the non genetic factors are the constituents that make up the ancestral environment which plays a role in variation among the offspring.
