Verified step by step guidance

1. Understand the definitions: A zygote is the cell formed when two gametes (e.g., sperm and egg) fuse during fertilization. A mature egg, also known as an oocyte, is a female gamete that is ready to be fertilized.
2. Consider the chromosome number: Recall that during fertilization, the chromosome number in the zygote doubles as it receives chromosomes from both the sperm and the egg, each of which carries half the number of chromosomes needed for a complete set in the organism.
3. Analyze the size comparison: Generally, the size of a zygote and a mature egg are similar since the zygote is formed directly from the fusion of a sperm and an egg.
4. Consider the cellular structure: A zygote is initially a single cell formed from the fusion of two gametes.
5. Examine the division process: After fertilization, the zygote undergoes mitotic divisions (not meiosis) to give rise to more cells and eventually develop into an embryo.
