Recombination
From Free net encyclopedia
Recombination usually denotes a genetic event that occurs during the formation of sperm and egg cells (especially in areas of study of biology topics). It is also referred to as crossing over (or change of phase).
Possible uses of the term are as follows:
- In biology, the process of Genetic recombination and meiosis, as summarized above.
- In chemistry, it is the state in which the hydrogen and oxygen gases 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 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 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.
