What blood type will a child have if the parents have AB and O blood types?
Disease description:
I have been preparing for pregnancy throughout this year, but there has been an issue that has been bothering me. I have AB blood type, and my husband has O blood type. I would like to ask the doctor, what blood type will a child born to parents with AB and O blood types have?
Doctor's answer (1)
Dr. Liu Feng
The blood type of a child born to parents with blood types AB and O is determined jointly by the parents' genetic makeup. According to the principles of genetics, a person with blood type AB carries both the A and B blood type genes, while a person with blood type O carries two O genes. When parents with these two blood types have a child, the child's possible blood type gene combinations can only be Ai or Bi.
1. A child with the Ai gene combination will have blood type A.
2. A child with the Bi gene combination will have blood type B.
Therefore, a child born to parents with blood types AB and O can only have blood type A or B, and cannot have blood type O or AB. This conclusion is based on the laws of genetics. It should be noted that although blood type inheritance generally follows predictable patterns, there may be special circumstances, such as gene mutations, although these are relatively rare.
