Does a child’s blood type usually follow the father’s or the mother’s?

The child’s blood type may be the same as the father’s blood type or the mother’s blood type.
A child’s blood type is related to both parents. It is possible for a child to have the same blood type as his or her dad or mom, or to have a different blood type than both parents.
Blood type is determined by genes on the ninth pair of chromosomes in the human body, and there are types AO, AA, BO, BB, AB, and OO, of which A and B are dominant genes and O is a recessive gene.
If the father’s blood type is A and the mother’s is O, the child’s blood type may be AO, the same as the father’s. If the father is A and the mother is B, the child’s blood type may be AB, which is different from both parents, but has acquired a gene from each parent.
There are many different blood types for children, if you need to determine your child’s blood type, it is recommended to go to the hospital and be tested by a professional doctor.
