Sentence examples for variance of a population from inspiring English sources

For determining the circular variance of a population of cells, the distribution in SF orientations was computed by summing the distributions from individual cells, with the histogram from each cell normalized so that each cell contributed equally to the total distribution.

Most measured variances will lie below this underlying value, as small samples typically do not capture the full variance of a population.

Following Darwin's lead, in 1922 Fisher had set out to investigate how the variance of a population is maintained or increased, and how it decays.

From the population genetics literature on asexual populations in which interference effects are at play, it is well known that an increase in the fitness variance of a population acts to slow adaptive evolution and make the characteristic size of adaptive mutations that fix larger.

Here, the z-score with 4.0> or <−4.0 indicates that the marker variance of a specific population is significantly greater, or smaller, than the variance mean.

The method was compared to a recently published core set method that maximises the variance of a hypothetical population that could be obtained by interbreeding the conserved breeds (MVO core set).

Imprinting can therefore have a significant effect on the total genetic variance and on the sex-specific components of variance of an inbred population.

Researchers use this method, and variations on it, to estimate the heritability of traits: the proportion of variance in a population explained by genes.

This is considered to be a strategy to unveil the spread of variance among a population that quite often is treated as one sole group.

In 2009, about a decade after the introduction of genome-wide association studies (GWASs), the term 'missing heritability' was introduced to describe the fact that only a small proportion of variance in a population attributable to additive genetic factors had been discovered by GWASs [ 3].

Heritability is expressed in terms of the proportion of the variance of a trait in a population that can be attributed to genetic differences.
