How do alleles of a particular gene differ from each other? Explain their significance.

(N/A) Alleles of a particular gene differ from each other due to specific changes,known as mutations,in the genetic material (a segment of $DNA$ or $RNA$). These changes result in different versions of the same gene. The significance of these different alleles is that they increase genetic variability or variation within a population. Such variations are essential for the processes of evolution and adaptation,allowing organisms to survive and thrive in changing environments.
