Determining Blood Type Compatibility
Before selecting a sperm donor, predict your blood type and Rh compatibility
When selecting a sperm donor, your blood type compatibility is important to consider. His blood type along with the blood type of the mother can be used to predict the possible blood types of their offspring. Please consult your physician about any ABO or Rh compatibility issues in a future pregnancy. Women that are Rh- who select a Rh+ donor may require treatment with Rhogam during pregnancy. It’s important to discuss this with your physician before you get started.

Blood Type Compatability Predictor FAQs
Is it possible for a child to have different blood type than both of its parents?
Yes, a child is able to have a different blood type than both parents.
Which parent decides the blood type of the child?
The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.
There are 4 maternal blood types and 4 paternal blood types, so there are 16 total combinations to consider when predicting the child’s blood type.

How are ABO alleles inherited by our children?
Introduction Human ABO markersBlood types and genotypes? How are ABO alleles inherited by our children?
Blood type calculator Rh factor | Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 different combinations to consider when predicting the blood type of children.
Blood Type Calculator
The following Blood Type Calculator lets you determine the *possible* blood type of a child, given the blood types of the two biological parents or the *possible* blood types of one biological parent, given the blood types of the child and the other biological parent. We emphasize "possible" because, in most cases, blood typing is not conclusive when attempting to determine, include or exclude an individual as the parent of an offspring. This calculator is based solely on theoretical principles. It would be a mistake to use this information to make any conclusions about your own family tree. Anyone wishing personal information about their own blood type inheritance is encouraged to contact their health care provider.Determine the *possible* blood types of the other biological parent
