Final answer:
During oogenesis, only one viable egg is produced. The other haploid cells, called polar bodies, will eventually degrade and not form mature gametes. The ovum has the potential to be fertilized by a sperm cell.
Step-by-step explanation:
In meiosis, the process of egg production, only one viable egg is produced. During oogenesis, a diploid cell undergoes meiosis, resulting in the formation of four haploid cells. However, three of these cells, called polar bodies, will eventually degrade and be reabsorbed by the body. The remaining haploid cell, called an ovum, has the potential to be fertilized by a sperm cell.
