Linkage disequilibrium
(LD): The tendency for two 'alleles' to be present on the same chromosome (positive LD), or not to segregate together (negative LD). As a result, specific alleles at two different loci are found together more or less than expected by chance. The same situation may exist for more than two alleles. Its magnitude is expressed as the delta
value and corresponds to the difference between
the expected and the observed haplotype frequency. It can have positive or negative values. LD is decreased by recombination. thus, it decreases every generation of random mating unless some
process opposing the approach to linkage equilibrium. Permanent LD may result from natural selection if some gametic combinations result in higher fitness than other combinations. Link to a lecture on
linkage disequilibrium.
