How Potential Child Blood Types Are Calculated

This calculation predicts the ABO blood group a baby might inherit by analyzing parental genetics. It uses Mendelian genetics to identify which alleles (gene versions) each parent can pass down.

We determine the blood type by matching one allele from each parent. If a dominant A or B allele is present, that blood type appears. Only if two O alleles combine does the child have Type O blood. This method accurately predicts all biological possibilities.

What Your Potential Child Blood Types Mean

The results show which blood types are genetically possible for your future children and the likelihood of each. This probability helps you understand the variety of outcomes based on your specific genetics.

Family Planning

If both parents are Type O, the result will be 100% Type O with no other possibilities. This provides certainty for parents with this specific combination.

Genetic Diversity

An A parent and a B parent can potentially have children with A, B, AB, or O blood. This creates the widest range of possibilities for a child.

Exclusions

An AB parent cannot pass on an O gene, so they cannot have a Type O child with another AB parent. Understanding these limits helps verify biological relationships.
