Verified step by step guidance

Understand the key terms provided in the question: Meiosis, Cytokinesis, Syngamy, and Mitosis. Each term represents a distinct biological process.
Define 'Syngamy': Syngamy refers to the fusion of two gametes (sperm and ovum) during fertilization, resulting in the formation of a zygote. This is the correct term for the process described in the question.
Define 'Meiosis': Meiosis is the process of cell division that reduces the chromosome number by half, producing gametes (sperm and ovum). It occurs before fertilization, not during the formation of a zygote.
Define 'Cytokinesis': Cytokinesis is the physical process of cell division, where the cytoplasm divides to form two daughter cells. This occurs during mitosis or meiosis but is unrelated to the fusion of gametes.
Define 'Mitosis': Mitosis is the process of cell division that results in two genetically identical daughter cells. It is not involved in the initial formation of a zygote but occurs later during embryonic development.
