Question

Describe briefly 4ways in which individuals with a particular trait may increase in population

Answer 1

The following are the four ways in which individuals with a particular trait may increase in population- 
1) Natural Selection- of variations brought through the course of time. 
2)Mutation- Slight changes in the genetic information of the offspring during fertilization. 
3)Geographic Isolation- where a population of species gets separated by their respective group due to physical/natural barriers. 
4)Genetic Drift and Isolation- An accident in small population of a species may also result in survival of species having a particular trait.
