disequilibrium

a situation where a state of EQUILIBRIUM has not been attained or, having been attained, ceases to be maintained. If there is a natural tendency towards equilibrium, the system is said to be stable. If the reverse is true, the system is said to be unstable. See COBWEB THEOREM, DYNAMIC ANALYSIS.

To test for intra- and interlocus linkage disequilibrium (LD) and recombination, the three genes were concatenated into a single sequence and arranged in the same order in which the genes are arranged along the chromosome (Tranquilli et al.
We note that a low level of misscoring can have substantial effects on estimates of Hardy-Weinberg equilibrium (see below), whereas estimates of allele frequency and linkage disequilibrium are not much affected.
The presence of a small number of haplotypes shared by multiple individuals is indicative of linkage disequilibrium (LD).
Linkage disequilibrium among markers in each generation was measured by the correlations among markers within each generation.
Difference in selection regimes between habitats, coupled with genetic variation for habitat preference, leads to linkage disequilibrium between performance and habitat preference loci.
In our study, the LD and haplotype analyses indicated the presence of strong linkages among APOB rs2163204, rs1042034, and rs676210, and strong linkage disequilibrium was observed between rs1042034 and rs676210.
