Following carrier testing, it is determined that both the husband and wife have sickle-cell trait. Which statement by the wife indicates correct understanding of autosomal recessive inheritance?
1. Because both my husband and I carry the trait but do not have the disease, I don't need to have prenatal testing because my baby will also be a carrier.
2. Because both my husband and I are both carriers, I don't need to have prenatal testing because all of our children will have the disease.
3. When I become pregnant, I need to have an amniocentesis or other prenatal test to determine whether my baby is affected with sickle-cell disease.
4. There is no use undergoing prenatal testing as sickle-cell anemia cannot be diagnosed prenatally.
