<h3><u>Explanation</u>;</h3>
- <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
- <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
