Stages of human development. 2 the product of fusion of an egg and sperm. Fertilization occurs with the fusion of two gametes, usually from different individuals, restoring the diploid state (Figure 7. Diploid Life Cycle. Fusion of the gametes gives rise to a fertilized egg cell, or zygote. (c) There is no natural death in single celled organisms like Amoeba and bacteria because the parental body is distributed among the offspring. During fertilization, a sperm and ovum unite to form a new diploid organism. Thus, it has twice the number of chromosomes as a gamete. While most animal species fall into the two types of gametes produced by two versions. Heterogamety, in the case of grasshoppers and some other insects, is a bit different. A glance at the huge variety of females and males across the animal and vegetable kingdoms will confirm that there is nothing else the sexes can be. Therefore, specialized sex cells known as gametes are produced through the process of meiosis. The zygote then undergoes many round of mitosis to produce an entire organism.
