| According to the Neo-Darwinist, natural selection can be classified into three categories: directional selection, disruptive selection, and stabilizing selection. |
| Resembling a homozygote has advantages under both frequency-dependent disruptive selection within populations and under divergent selection between environments. |
| A popular theory has proposed that anisogamy originated through disruptive selection acting on an ancestral isogamous population. |
| 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. |
| Disruptive selection favors individuals with either of the opposite extremes of a trait and discourages moderation. |
| We found that there is pronounced opportunity for disruptive selection on brambling egg coloration. |
