The module discussed three key variables that influence the effect of a teratogen. A) Describe these three variables. B) Then, name an example of a teratogen. C) Finally, come up with a realistic scenario (that is, make up a story) about a mother and child for whom this teratogen might play a role, and describe how the three key variables influence the effect of that specific teratogen in this specific example. - A.
Age/ Gestation at which the baby is exposed to the teratogen. If it is at a vital point when the organs are developing the baby is at risk at more harm. The amount of teratogen the baby is exposed to. The more exposure correlations to the more damage to the baby.
The susceptibility of a teratogen that is present with the mother may/ may not pass to her child.
