Variable expressivity refers to how different individuals may have the same genotype but express different phenotypes. This suggests that genetic factors are not the only determinants of a trait and that environmental factors can also influence how genes are expressed. This phenomenon contradicts the idea of genetic determinism, which suggests that an individual's genes fully determine their traits.
