Can Persons Of Same Blood Group Be Married Together?
Dear Doctor,We found a suitable match for my sis. They both are B +ve. Our parents fear that with same blood group the bride and groom may give birth to thalasemic babies. Please confirm if this is true or not. And also advice the blood test to be done for the boy and girl to check if they are thalasemia minors or not.

Hello and welcome to HCM,
Marriage between individuals of same blood group does not cause thalassemia in children.
However, if either of the parent is having thalassemia minor or major then there are chances of passing on the genetic defect to the child.
I suggest you to get hemoglobin chain analysis to know whether there is any defect of hemoglobin chains or not.
Thanks and take care
