genetic variance

The genetic variances also change relative to those of panmixia.

Therefore, females are actually selecting for high genetic variance.

Thus any condition-dependent trait "captures" the overall genetic variance in condition.

Theoretically, their lack of genetic variance could put cheetahs at greater risk from infectious diseases.

Thus genetic variance remains in populations through gene flow across environments or generation overlap.

The product of the relative frequencies, , is a measure of the genetic variance.

But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.

A body of literature over the last two decades suggests that the reason lies in the genetic variance of a sexually produced offspring.

One study found no increase in additive genetic variance for female fertility with age in Drosophila.

Under directional selection on , the loci underlying and may lose all genetic variance.

This suggests that it is important to protect each population in order to conserve the genetic variance in each.

Genic capture is a hypothesis explaining the maintenance of genetic variance in traits under sexual selection.

Daphnia from the early 1960's, before the lake became heavily polluted, showed wide genetic variance in terms of sensitivity to the cyanobacteria.

The pattern of standing genetic variance has been exploited in investigations of the evolution of ageing.

The variance will include terms for genetic variance (since they did not all get the same genotype) and environmental variance.

Innate needs, like that for caloric intake, are genetically determined and therefore shared (with the usual genetic variance) among all humans.

Model organisms are made standard by limiting genetic variance, creating, hopefully, this broad applicability to other organisms.

In fact, predators are known for low genetic variance, along with most of the top portion of the tropic levels of an ecosystem.

Congenital defects, genetic variance, and developmental issues are of greater concern to pediatricians than they often are to adult physicians.

Though usually helpful, it may be bad because small population sizes are used, so genetic variance can be small due to interbreeding between the animals.

This definition, which is due to Wright, illustrates that F measures the amount of genetic variance that can be explained by population structure.

This obviously increases benefits in regard to distance traveled, but also reduces the amount of genetic variance, increasing the likelihood of inbreeding.

Standing genetic variance has also been used to study the sign and magnitude of genetic correlations between ages, for survival probability and fertility.

Prior to recent studies, V. jacobsoni was considered homogeneous; however, current research has detected genetic variance among populations by using genetic markers.

Quantitative genetics considers genetic variance and covariance and can facilitate identifying the constraints needed for a satisfactory optimization model.
