When two parents of opposite sex participate in a reproductive process and also involve the formation and fusion of gametes are called sexual reproduction. The gametes are haploid in nature formed by reduction division. The fusion of male and female gametes to form a diploid structure called the zygote. This process is called fertilization or syngamy. The size and shape of male and female gametes are either similar or dissimilar. The fusion between similar gametes is called isogamy. In isogamy, both male and female gametes are similar in their size and shapes. These are called homogametes or isogametes. Example: Monocystis.

When two parents of opposite sex participate in a reproductive process and also involve the formation and fusion of gametes are called sexual reproduction. The gametes are haploid in nature formed by reduction division. The fusion of male and female gametes to form a diploid structure called the zygote. This process is called fertilization or syngamy. Hologamy is a type of sexual reproduction in protozoa in which gametes are not formed. It includes the fusion of two mature organisms that do not form gametes but behave as gametes. This type of reproduction is found in Trichonympha.
