Summary Introduction
To define: Sexual reproduction and to explain why meiosis contributes to one of its great strength.
Introduction: Reproduction is the biological process through which new individual organisms are produced from their parents. It is the ubiquitous properties of life. It is essential for evolution, since the ceaseless replacement of predecessors with new life gives animal population. There are two types of reproduction namely asexual reproduction and sexual reproduction.
