The formation of new combinations of genes as a result of segregation in crosses between genetically different parents; also the rearrangement of linked genes due to crossing-over.
The joining of genes, sets of genes, or parts of genes, into new combinations, either biologically or through laboratory manipulation (e.g., genetic engineering).
The formation of new gene combinations as a result of sexual reproduction.
In the measurement of radiation by ionimetric methods it is necessary to collect the liberated charges to arrive at a value of total charge per unit mass of air. Recombination of ions will lower the value collected and will cause an underestimation of dose, particularly in intense fields. A technique for determining the magnitude of ionic recombination is routinely applied in accurate dosimetry.
