Detailed explanation-1: -Disruptive selection is a type of selection which reduces the reproduction of organisms with intermediate traits and allows organisms with extreme traits to reproduce more. Hence, disruptive selection favours the extreme phenotypes and eliminates the intermediate ones.

Detailed explanation-2: -In disruptive selection both extreme traits are favored. For example, if both the small and large turtles were favored and the medium turtles were being eaten, this would be an example of disruptive natural selection.

Detailed explanation-3: -Diversifying (or disruptive) selection: Diversifying selection occurs when extreme values for a trait are favored over the intermediate values. This type of selection often drives speciation.

Detailed explanation-4: -Disruptive selection can lead to a bimodal distribution of trait values and therefore can result in an increase in the variance of a trait without a change in its mean.

Detailed explanation-5: -Disruptive Selection☆ Disruptive selection occurs when individuals of intermediate phenotype are less fit than those of both higher and lower phenotype, such that extremes are favored. This may occur if there are two diverse food sources or predators with diverse preferences for, say, size of prey.
