link·age dis·e·qui·lib·ri·um

a state involving two loci in which the probability of a joint gamete is not equal to the product of the probabilities of the constituent genes. The difference between these quantities is the increase of the disequilibrium; there are many causes of the disequilibrium.

linkage disequilibrium

The occurrence of combination of genes (linkages) in a population more often, or less often, than would be expected from their distance apart in the genome.

linkage disequilibrium

a nonrandom association of alleles at different loci in a population, as is produced when two loci are closely linked and selection operates to keep certain gene combinations together.
