Summary Introduction
Introduction: The sexually reproducing organisms give rise to unique progenies that contains genes from both of its parents. Such reproduction gives evolutionary advantages than the asexually reproduced ones to survive in the unfavorable condition. Sexual reproduction is a reproduction where the offspring are produced that inherits genes from both of its parents. It will not be exactly as its parents but will be mixed and showed diversity after each generation. Variations are seen among them as they possess randomly mixed genetic traits from both their parents and give birth to unique young ones. Such offspring are able to survive better in unfavorable conditions than the asexual ones.
