An increase in theadditivevarianceafter bottlenecks will occur only if its ancestral value is minimal or very small.
From theCambridge English Corpus
They have shown that linkage disequilibrium can lead only to a small transient increase in the derivedadditivevariance, above that expected from drift alone.
From theCambridge English Corpus
Summarizing, for the epistatic models studied, occasional increases in the derivedadditivevariancecan be observed.
From theCambridge English Corpus
In those situations, the ancestraladditivevarianceis very small and the ancestral non-additivevarianceis maximum.
From theCambridge English Corpus
So far, this discussion has been limited to investigating the consequences of population bottlenecks on the mean andadditivevariancegenerated by two-loci epistatic systems.
From theCambridge English Corpus
In this paper, we have theoretically investigated the effect of successive population bottlenecks on the mean and theadditivevariancegenerated by two-loci systems.
From theCambridge English Corpus
Nevertheless, the effect of linkage disequilibrium on theadditivevarianceafter multiple bottlenecks has not been analysed.
From theCambridge English Corpus
However, those effects were small relative to theadditivevarianceof the base population.
From theCambridge English Corpus
Therefore, dominance can be considered as the primary cause of an increase in the ancestraladditivevarianceafter bottlenecks.
From theCambridge English Corpus
These experiments used changes in the ratio of the dominance variance toadditivevarianceto reject single locus overdominance as the primary cause of heterosis.
From theCambridge English Corpus
However, large recombination rates increase the contribution of the ancestral epistatic variance to the derivedadditivevariance, but decrease it to the between-line variance.
From theCambridge English Corpus
Moreover, for recessive alleles at low frequencies, the enhancement ofadditivevarianceafter bottlenecks will always be penalized by a large inbreeding depression, excepting the case of favourable recessives.
From theCambridge English Corpus
If the expression ofadditivevarianceis increased by the stressful conditions as suggested by these results, the response to selection will be greater under some combinations of extreme conditions.
From theCambridge English Corpus
On the other hand, with weak additiveiadditive and reinforcing (multiple dominant favoured) epistasis, the ancestral mean surface has a single peak and the ancestraladditivevariancesurface shows no minimum.
From theCambridge English Corpus
In parallel, intermediate gene frequencies at both loci correspond to minimumadditivevariance(two ridges) or to a saddle of the additive variance surface (one ridge).
From theCambridge English Corpus
Mapped factors therefore account for about 26 % ofadditivevariance.
From theCambridge English Corpus
It is not clear, however, whether inbreeding depression can be counteracted by increasedadditivevariance and, therefore, the impact of the latter on the outcome of natural selection is uncertain.
