Question

These changes occur during the fetal period, which begins at the end of the embryonic period (around 9 weeks after conception) and continues until birth. During this time, prenatal development focuses on growth and refinement of existing structures. Rapid weight gain and active movement of limbs are characteristic of this stage, as is the development of more distinct facial features. The germinal period refers to the very early stage of development, immediately following fertilization. The embryonic period, which is marked by the formation of major organ systems, occurs between the germinal and fetal periods. Monozygotic refers to twins that develop from a single fertilized egg that later splits into two, and is not a developmental period.
