Beta Thalassemia: When only one parent has beta thalassemia trait and the other does not have a blood trait, there is essentially no chance of having a baby with any form of beta thalassemia disease. However, each child has a 50% (or 1 in 2) chance to inherit beta thalassemia trait from the parent. Any Grandchildren would have a 25% chance of inheriting the Beta Thalassemia trait but not the disease.
