............

Answer 1

Answer:

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

1. Sexual reproduction results into variations.
2. The individuals with special traits survive the attack of their predators and multiply while the other will perish.
3. Genetic drift provides diversity without any adaptation.
4. Variations in the species may lead to increased survival of the individuals.

Answer 2

Answer:

Four ways in which individuals with a particular trait may increase on population are:

1.) Organism with particular trait may be naturally selected which can provide a survival advantage. This I known as natural selection.

2.) An accident in small populations may result in surviving of organisms with a particular variant only. 

3.) A species can be separated by their respective group because of physical barriers. This is called geographic isolation.

4.) A slight change in genetic information cam also help in increase in population. This is known as mutation.
