The four ways in which individuals with a particular trait may increase in a population are as follows:

Sexual reproduction results into variations.

The individuals with special traits survive the attack of their predators and multiply while the other will perish.

Genetic drift provides diversity without any adaptation.

Variations in the species may lead to increased survival of the individuals.

Traits arise due to variations which occur due to sexual reproduction of inaccuracies during DNA copying or environmental factors. Now, the individuals with a particular trait may increase in a population due to the following factors :

(i) Natural selection: Those variations which give survival advantage to an organism are selected in nature and such traits increase in population.

(ii) Genetic drift: It occurs due to change in gene frequency due to accumulation of particular type of genes.

(iii) Geographical isolation: It leads to change in gene frequency leading to expression of one type of traits in a geographically isolated population.

(iv) Migration: It leads to flow of a particular type of gene in a specified population.
