disruptive selection in a sentence

Examples

1. Disruptive selection is inferred to oftentimes lead to sympatric speciation through a phyletic gradualism mode of evolution.
2. When disruptive selection is based on intraspecific competition, it in turn promotes ecological niche diversification and polymorphisms.
3. Disruptive selection can initially rapidly intensify divergence; this is because it is only manipulating alleles that already exist.
4. Disruptive selection can be caused or influenced by multiple factors and also have multiple outcomes, in addition to speciation.
5. The most popular, which invokes the disruptive selection model, was first put forward by John Maynard Smith in 1966.
6. When intraspecific competition is not at work disruptive selection can still lead to sympatric speciation and it does this through maintaining polymorphisms.
7. :: Killing off 99.9 % of the harmful bacteria, for example, increases the likelihood of superbugs via disruptive selection.
8. Secondly, disruptive selection is selection for extreme trait values and often results in two different values becoming most common, with selection against the average value.
9. The uncommon disruptive selection also acts during transition periods when the current mode is sub-optimal, but alters the trait in more than one direction.
10. Disruptive selection is seen in high density populations rather than in low density populations because intraspecific competition is more common when accompanied by a higher density population.
