Quizplus · Accepted Answer

The implantation of the fertilized egg in the uterine lining occurs during the germinal stage of prenatal development. The germinal stage lasts for the first 2 weeks after conception and is characterized by the fertilization of the egg, cell division, and the formation of the blastocyst, which implants in the uterine lining. The embryonic stage follows this and goes on until the end of the eighth week after conception. The fetal stage lasts from week 9 until birth. Teratogens refer to any substances or agents that can cause developmental abnormalities in the fetus.
