Disruptive Natural selection

Disruptive selection favors the survival of individuals at both extremes of a range, rather than the  intermediate.

Increase variance in the population because select those phenotype which are away from mean.

It maintain balance polymorphism and maximum selection coefficient value.

Negative assortative mating

People only select mates who are phenotypically different from themselves for selective traits. 

Increases the frequency of heterozygous genotypes (Aa).
