Recombination
Recombination usually refers to the biological process of genetic recombination and meiosis, a genetic event that occurs during the formation of sperm and egg cells. It is also referred to as crossing over or change of phase.
Other possible uses of the term are as follows:
- In chemistry, it is the state in which the hydrogen and oxygen gases which form within the battery cell during charging are recombined to form water.
- In physical cosmology, the event after the Big Bang during which electrons became bound to nuclei. After the decoupling of matter and radiation, which happened at about the same time as recombination, ambient photons could travel freely, and are visible today as the Cosmic Microwave Background.
- In physics, Lord Kelvin's Knot theory describes atoms as knots of swirling vortices in the æther. This is helpful in understanding the mechanics of matter absorbing and emitting radiant energy, during reionization and ionization, in the Ionosphere.
- In Astronomy and atomic physics, recombination refers to an electron becoming bonded with an ionized atom.
- In evolutionary computing, recombination is another name for crossover.
- In solid state physics of semiconductors, carrier recombination is a process by which electrons and electron holes are mutually eliminated, and is balanced with carrier generation to establish the carrier density at thermal equilibrium.
