How can prenatal environmental factors influence a child’s development besides heredity?

  1. They have no prenatal influence whatsoever, because only inherited genes matter before a child is born
  2. Prenatal nutrition, maternal health, stress and toxins affect growth and brain
  3. Only physical traits like eye color change prenatally
  4. Only environment after birth matters
Show answer and explanation

Correct answer: Prenatal nutrition, maternal health, stress and toxins affect growth and brain
