The process in which two gametes unite is called fertilization. The fertilized cell that results is referred to as a zygote. A zygote is a diploid (or 2N) cell, which means it contains two copies of each chromosome. Human gametes are produced by Human gametes are formed in the gonads by cell division known as meiosis. In this type of division, a diploid parent cell divides twice to form four haploid cells. 2021-01-22 · This process is called cytokinesis and usually takes place during telophase. Meiosis.
