Sentence examples for between migration and drift from inspiring English sources

The interaction between migration and drift is especially interesting.

Therefore, differentiating between migration and drift and temporal population subdivision is difficult.

One assumption of particular relevance to this study is that of equilibrium between migration and drift, which is violated in populations that have recently become completely isolated.

Classic models of population genetics consider the source of genetic differentiation between populations (F ST ) to result either from an equilibrium between migration and drift (island model) or from drift since the time of divergence (isolation model).

Such recent species complexes often have not yet achieved equilibrium between migration and drift, a condition which will strongly influence the outcome of studies aiming at quantifying gene flow if recent divergence is not taken into account.

Analysis in 2-MOD confirms that the four populations in this landscape have been in migration drift equilibrium and that the current levels of genetic structure are a result of equilibrium between migration and drift.

At a broader scale, if the differentiation between populations depends on the distance between them, as a result of equilibrium between migration and genetic drift, there is an isolation by distance effect [ 13].

As developed above, the approaches to infer demographic parameters from genetic data classically rely on neutral models that assume a balance between migration and genetic drift (Whitlock and McCauley 1999).

Therefore we obtain equation (14) and (15), which mean migration and drift are equal between groups.

However, in changing environments, populations are frequently out of equilibrium with patterns of migration and drift.

Further work will shed light into the relative contribution of migration, and drift versus natural selection in shaping the patterns of genomewide variation in the European population.
