Detailed explanation-1: -In other words, sexual reproduction involves the fusion of female gamete (ovum) and male gamete (sperm). The fusion of these gametes occurs during fertilization. The result of the fusion is the formation of a zygote. The zygote develops into an offspring that is genetically distinct from the parent organisms.

Detailed explanation-2: -In sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation. Sex cells are also known as gametes.

Detailed explanation-3: -Sexual reproduction occurs in a variety of ways in animals. In some species, such as fish, the male releases sperm over the eggs after the female has laid them. In other species, such as birds and most mammals-including human beings-the male releases sperm into the female reproductive tract.

Detailed explanation-4: -Reason: In asexual reproduction, there is no formation and fusion of gametes.
