** genetic interactions — Mendel's law of segregation — genetic mosaic — maternal effect — penetrance — complementation — suppression — epistasis — genetic linkage

** chromosomal effects: chromosome — haploid — diploid — polyploidy — dosage effect — inbreeding

** Causality and Dependence ( cause and effect )

** Self-focusing, an effect due to the Optical Kerr effect ( and possibly higher order nonlinearities ) caused by the spatial variation in the intensity creating a spatial variation in the refractive index

** Self-phase modulation ( SPM ), an effect due to the Optical Kerr effect ( and possibly higher order nonlinearities ) caused by the temporal variation in the intensity creating a temporal variation in the refractive index

** Optical solitons, An equilibrium solution for either an optical pulse ( temporal soliton ) or Spatial mode ( spatial soliton ) that does not change during propagation due to a balance between diffraction and the Kerr effect ( e. g. Self-phase modulation for temporal and Self-focusing for spatial solitons ).

** Electroabsorption: general change of the absorption constants

** Quantum-confined Stark effect: change in the absorption in some semiconductor quantum wells

** Electrochromic effect: creation of an absorption band at some wavelengths, which gives rise to a change in colour

** Pockels effect ( or linear electro-optic effect ): change in the refractive index linearly proportional to the electric field.

** Kerr effect ( or quadratic electro-optic effect, QEO effect ): change in the refractive index proportional to the square of the electric field.

** electro-gyration: change in the optical activity.

** Phosphorylation of src tyrosine kinase ( pronounced " sarc ") by C-terminal Src kinase ( Csk ) induces a conformational change in the enzyme, resulting in a fold in the structure, which masks its kinase domain, and is thus shut " off ".
