The three things that influence the severity of the damage done by a teratogen are:
a)Timing : It means the time period of the pregnancy when the child is exposed to teratogen. The dffect is that brain and nervous system can be harmed.
b)Exposure: It means the amount of teratogen used and the child has been exposed to.The defect is that it causes harm if the dose is big but no harm if the dose is small.
c)Genetic variability:Certain genes are affected by the teratogen while others are not. The defect is that whether the genes is affected or not.
The examples of teratogens include Phenytoin,Varicella .Folic acid is important because Folic acid is it is a form of B vitamin which is called as folate.
