  3. maternal effects are only seen with viral teratogens
  4. genetic factors are not present with viral teratogens

4. Primary infection of the mother, rather than re-activation, tends to have a worse fetal consequence.

  1. True
  2. False

5. A fetus is particularly susceptible to rubella infection when maternal infection occurs during what stage of pregnancy?
