Detailed explanation-1: -sexual selection, theory in postulating that the evolution of certain conspicuous physical traits-such as pronounced coloration, increased size, or striking adornments-in animals may grant the possessors of these traits greater success in obtaining mates.

Detailed explanation-2: -The Hardy-Weinberg principle assumes random mating: mate selection without regard to genotype. Non-random mating means that mate selection is influenced by phenotypic differences based on underlying genotypic differences.

Detailed explanation-3: -Non-random mating can be assortative, when individuals are more likely to mate with similar individuals (e.g., individuals having the same genotype or phenotype), or it can be disassortative, when individuals prefer to mate with dissimilar individuals.

Detailed explanation-4: -Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. Any departure from random mating upsets the equilibrium distribution of genotypes in a population. This will occur whether mate selection is positive or negative assortative.

Detailed explanation-5: -Nonrandom mating is a phenomenon that individuals choose their mates based on their genotypes or phenotypes. Examples of this kind of mating occur in species like humans, peacocks, and frogs.
