When does the influence of heredity exist?

• A. Before the child is conceived
• B. After birth
• C. During adolescence
• D. Only during pregnancy

Answer: (A)

Heredity begins to influence development from the very start because the genetic material that will shape the child is already present in the parents’ reproductive cells long before conception. Eggs and sperm carry genes, and when fertilization happens, those genes combine to form the child’s unique genetic blueprint. So the potential traits and how development unfolds are determined at conception, making the earliest moment heredity can exert influence the time before the child is conceived. After conception, pregnancy and later life continue to reflect that genetic makeup, but the root of hereditary influence is already in place as the parental genes come together.
