Genetics.
- : the formation of new combinations of genes, either naturally, by crossing over or independent assortment, or in the laboratory by direct manipulation of genetic material.

The rate of recombination depends upon the product of the number of each sign present in unit volume.
The ionic density is therefore high, and recombination very rapidly removes the ions after they are formed.
Much of the ionisation in gases is again undone by recombination before diffusion leads to the separation of the ions.
This "initial recombination" is greatest towards the end of the path of the ray where the ionisation is a maximum.
In the former, initial recombination may obscure the intense ionisation near the end of the range.
