Selection that acts, over evolutionary time, to enhance traits that increase an individual's ability to mate frequently or with quality partners is known as sexual selection.

Explanation:

Sexual selection : The process through which males and females attempt to maximise their chances of reproductive success is called sexual selection. It is a form of natural selection. Charles Darwin suggested sexual selection. Animals compete with others of the same species for the chance to mate.

For example: Male widow-bird grows exceptional long tail feathers, females lack tail feathers.

Sexual selection.

Explanation:

This concept was proposed by the scientist named Darwin in his theory. This concept can be used in the explanation of competition and the ability of organisms or species to select desired partners or mates naturally. And this selection is done because an organism or a specie of organism wants to produce offsprings with featured or characteristics that are distinct. The sexual selection can also also be done by which an organism or specie select in an intersexual manner that is selection of another species different from the the species the organism belongs to. It can also be done by selecting mates or partners with good features within the same specie.
