The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).
The expression of genes in an organism can be influenced by the environment, adding the external world in which the organism is or where it develops, as well as the organism's internal world, which includes such factors as its hormones and metabolism.
