. If both parents have sickle cell trait, there is a 25% chance their offspring will have sickle cell anemia.
. If one parent has sickle cell anemia and the other does not, their offspring will have a 50% chance of having sickle cell trait.
. If both parents carry sickle cell trait, there is a 50% chance their offspring will have sickle cell trait.
. If one parent has sickle cell anemia and the other carries trait, their offspring will have a 50% chance of having sickle cell anemia.
. If one parent has sickle cell anemia and the other does not, their offspring will have a 25% chance of having sickle cell anemia.
Test-Taking Tip
Write out a mendelian square when considering heredity. See the table below, which uses the letter "S" to represent sickle cell trait and "s" to represent no trait, with "SS" indicating an individual with sickle cell disease. In the example, a parent with sickle cell disease is paired with a parent who carries the trait, with a resulting 50% chance that their offspring will have the disease or carry the trait.
| S | S | |
| S | SS | SS |
| s | Ss | Ss |
