Sentence examples for counteract drift from inspiring English sources

These results suggest that selection on MHC is not strong enough to counteract drift that results from population fragmentation, isolation and bottleneck.

Although there have been a number of studies correlating bottlenecked populations with reduction in MHC variation [ 6, 10, 61], there have also been several studies showing the opposite, as balancing selection appears to counteract drift [ 12, 60, 62, 63].

Nonetheless, the inclusion of several African populations with very different demographic histories (counteracting drift effects), and the study of spatial autocorrelation with extremely conservative significance cutoffs could be expected to reduce these spurious signals.

Such structures would need either some form of propulsion to counteract any drift, or some way to repel the surface of the sphere away from the star.

It is important to emphasise that although a very small amount of migration is enough to counteract genetic drift, not rejecting panmixia does not equate to open populations that are capable of seeding degraded neighbouring or distant reefs.

Also, when there are many genes (compared to Goddard's two-loci example), it makes sense to prioritize the loci according to their predicted effect in order to counteract random drift where it matters most.

Strong selection at functional loci may counteract genetic drift and maintain adaptively important genetic variation (Aguilar et al. 2004; Piertney and Oliver 2005; Oliver and Piertney 2012), even in populations that have undergone extreme genetic bottlenecks (Aguilar et al. 2004; Piertney and Oliver 2005; Whittaker et al. 2012).

The controller must counteract slow-drift oscillations due to waves and static offsets induced by current, wind and waves.

While fewer introduced individuals may have led to reduced diversity in the parasite, admixture between different founder populations may have counteracted genetic drift and bottlenecks.

Their ability to adapt to new environments and hosts is likely to be affected by their degree of genetic diversity, with gene flow between distinct populations counteracting genetic drift and increasing effective population size.

Equally importantly, 'densification' counteracts the drift to the suburbs with its demand for more roads and bridges and associated increases in carbon emissions from vehicles.
