Sentence examples for bottleneck period from inspiring English sources

In the 'gene flow at bottleneck' model, gene flow occurred only in the bottleneck period.

In the 'gene flow after bottleneck' model, gene flow occurred after the end of bottleneck period.

During this prolonged bottleneck period, S. fruticosa was grown only in gardens and vineyards surrounding local settlements.

Interestingly, all three theories have their non-scientific resonances, "everything is relative", "everything is subjective", and "everything was created" descending from the bottleneck period.

The results indicated that bidirectional gene flow during the bottleneck period between the populations is the most likely scenario (Table  3).

At time t1, which we allow to occur either within or before the bottleneck period (i.e. we do not a priori determine the relative size of tBS and t1), the Norwegian population is sampled, and prior range for t1 is set to between 500 and 1,700 yr BP.

Especially, the first three processes could result in species undergoing bottleneck periods during which genetic drift could play a large role in fixing random mutations.

However, we also tested bottleneck periods of different lengths, as well as a gradual increase of the population size after the colonization, to check the sensitivity of the results to this assumption.

Thirdly evolutionary bottlenecks (periods with smaller population sizes) have shorter coalescence times, reducing the observation window further.

Bottlenecks—short periods where the population size is drastically reduced before recovering in size are commonly detected demographic events.

In particular, we found a significantly lower migration rate among populations in SEA than in NEA, suggesting that SEAs underwent severe bottlenecks or periods of substantial isolation, likely due to the mountainous reliefs of this region.
