stabilizing selection उदाहरण वाक्य
उदाहरण वाक्य
- Because most traits change little over time, stabilizing selection is thought to be the most common type of selection in most populations.
- However, a meta-analysis of studies that measured selection in the wild failed to find an overall trend for stabilizing selection.
- Stabilizing selection commonly uses negative selection ( a . k . a . purifying selection ) to select against extreme values of the character.
- Alternatively, the values of the behavioural traits are not maximized by directional selection, but rather are under the influence of stabilizing selection.
- Stabilizing selection acts to hold a trait at a stable optimum, and in the simplest case all deviations from this optimum are selectively disadvantageous.
- One study shows that a small influx of immigrants with a tendency to cooperate less can generate enough genetic variability to stabilize selection for mutualism.
- Averageness has been a result of stabilizing selection whereas facial paedomorphosis or juvenile traits are a result of directional selection ( Wehr, 2001 ).
- This phenomenon, which he calls " stabilizing selection, " puts genes and environment on a par in secondary importance compared to the epigenetic system.
- To compare the effects of directional and stabilizing selection on facial paedomorphosis Wehr used graphic morphing to alter appearances to make faces appear more or less juvenile.
- However, there is no qualitative difference in directional selection on C between stabilizing selection ( i . e . no sexual selection ) and directional selection on T.
