WebMendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. These principles were initially controversial. When Mendel's theories were … Web3.1 The Physics of Diffusion. Diffusion is the kinetic process that leads to the homogenization, or uniform mixing, of the chemical components in a phase. Although mixing in a fluid (liquid or gas) may occur on many length scales, as induced by macroscopic flow, diffusive mixing in solids, by contrast, occurs only on the atomic or molecular level.
