To address these issues, we surveyed 15 populations of Mexican spadefoot toad tadpoles, Spea multiplicata, and Examples of disruptive selection in a sentence, how to use it. 16 examples: With disruptive selection on a single trait, divergence must involve a fitness… Theory suggests that speciation with gene flow is most likely when both sexual and ecological selection are divergent or disruptive. Divergent sexual and natural selection on the visual system have been demonstrated before in sympatric, morphologically similar sister species of Lake Victoria cichlids, but this does not explain the subtle morphological differences between them.

In disruptive selection, the normal curve hits extremes and bypasses levels of a trait in the middle. It is the rarest form of selection. Disruptive Selection This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Disruptive selection and Directional selection are types of selection that occur in organisms within an environment.

Disruptive selection can be a precursor to speciation. Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection is the opposite of disruptive selection. This is an example of underdominance (heterozygote disadvantage) leading to disruptive selection.
