In my Feature Article “It’s Not Your Grandmother’s Genetics Anymore!” (American Biology Teacher, 76, 224–229), I inadvertently stated that women of childbearing age who regularly take vitamin A in the first weeks of their pregnancy are less likely to give birth to a child with spina bifida. The supplement that women should take to reduce the risk of having a child with spina bifida is folic acid, not vitamin A. I apologize for this error.
