Sentence examples for mutational variance in from inspiring English sources

It also shows the role of mutation rate, and the mutation-by-network size interaction (i.e., mutational variance), in shaping persistence time.

Rather, the invariance of transcript abundance among MA lines was consistent with low segregating variation in the inbred ancestral line and with the estimated 34 mutations per MA line being insufficient to generate detectable mutational variance in most genes.

We derive analytical results based on the so-called House of Gauss approximation for the genetic variance, the mean phenotype, and the mutational variance in the balance of the evolutionary forces.

In these models, this matrix has a single dimension, represented by the eigenvector m max, with the amount of mutational variance in the trait set that is due to the pleiotropic covariance described by the eigenvalue of m max.

Furthermore, the mutational variance in the common factor, m max, was significantly lower in the shuffled than in the observed data (paired t-test: t = 9.801, d.f. = 676, P < 0.0001).

For instance, the presence of a TATA box in the promoter region is associated with high mutational variance in expression (Landry et al. 2007), as well as increased environmental plasticity and expression variation across species (Tirosh et al. 2006).

Such increases in mutational variance would occur without increases in mutation rate.

Estimates of mutational variance from mutation accumulation studies are rarely matched with simultaneous estimates of the standing genetic variance in the same traits, measured under the same conditions (Houle et al. 1996).

Differences in mutational variance have been found among strains of Caenorhabditis elegans (Baer et al. 2005).

Such increases in mutational variance could then contribute to additive genetic variance (VA), upon which selection could act.

First, we used a LRT to contrast a model that estimated the common mutational variance with a model in which only trait-specific mutational variances were estimated.
