Summary Introduction

The change in the heritable features of the biological populations over successive generations is called evolution. These characteristics are the expressions of genes that are passed on from parent to progeny during reproduction. The diverse characteristics tend to occur within any given populations due to genetic recombination, mutation and other sources of genetic variations. There are four types of mechanism of evolutionary changes includes natural selection, genetic drift, gene flow and mutations.
