The blood type and Rh factor of a pregnant woman and the father of her baby can affect what blood type the baby has. It will also influence the antibodies the mother’s body makes as an immune response to foreign matter in her body such as bacteria, sperm and even an embryo.
Which parent determines the blood type of the child?
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
What blood type are not compatible for pregnancy?
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
Does your partner’s blood type affect pregnancy?
Although your blood and your baby’s blood typically do not mix during pregnancy, a minimal amount of your baby’s blood and your blood could come in contact with each other during delivery. If there’s an Rh incompatibility and this happens, your body might produce Rh antibodies against Rh factor.
Does it matter if the father is Rh negative?
If you are already Rh-sensitized or become sensitized while pregnant, close monitoring is important to determine whether your fetus is being harmed. If possible, the father will be tested to see if the fetus could be Rh-positive. If the father is Rh-negative, the fetus is Rh-negative and is not in danger.
Do siblings have same blood type?
