WebbMuch less commonly, a zygote can divide into two separate offspring during early development. This results in the birth of monozygotic (or identical) twins. Although the zygote can split as early as the two-cell stage, splitting occurs most commonly during the early blastocyst stage, with roughly 70–100 cells present. WebbImplantation, typically, occurs 7-12 days after conception. The cells start to divide in the embryo, developing into a zygote. The zygote implants itself to the uterine walls. As soon as implantation is completed, the zygote releases a hormone called hcG, which is used by pregnancy tests to determine pregnancy. Common Symptoms of Implantation
