genetic disequilibrium

ge·net·ic dis·e·qui·lib·ri·um

a state in the genetic composition of a population that under selection may be expected to change toward an equilibrium or absorbing state.

The polymorphism at both sites, A1915G of ADRA1B and T6146C of PPARGC1B, were evaluated and found to exhibit significant genetic disequilibrium between the A and G alleles of ADRA1B and the T and C alleles of PPARGC1B (p<0.05).
Both of these SNPs were found to be under genetic disequilibrium possibly due to allele A (ADRA1B) or allele T (PPARGC1B) being naturally one of the predominant alleles during genetic evolution, thus being more conserved and more common than other alleles in this population.
For the current study, the sample content (75) reached the sampling requirement, which indicated that the genetic disequilibrium should not be attributed to the samples but to the excessive artificial selection or inbreeding and other factors of the Chinese Yellow Quail groups.

msp-1 is associated with protection, especially the highly conserved [msp-1.sub.19]-kDa fragment (45); this is a major reason to consider msp-1 block-2 (and loci in genetic disequilibrium with msp-1 block-2) specifically rather than as only a marker for overall MOI.
pulchellum (and the maintenance of genetic disequilibrium).
Genetic disequilibrium found in the present study showed that the selection could be effective for BB genotype in Holstein, but not EAR cattle.
Genetic disequilibrium may either increase or decrease genetic structuring within versus among subpopulations, depending on founder conditions.
It is unlikely, however, that the antagonism between fitness components observed in the present case was the result of genetic disequilibrium. Prior to establishment of the B and O lines, the base population was maintained in a manner designed to reduce any initial disequilibrium, and to minimize creation of disequilibrium by genetic drift.
