Child Blood Type Calculator

Tangazo
Zana zote

See every blood type your child could inherit from the parents' ABO and Rh blood groups, with probabilities from a full Punnett-square analysis.

Most likely type – –
Based on ABO and Rh Punnett squares. When a parent's phenotype allows several genotypes (e.g. type A can be AA or AO), each is treated as equally likely, so real-world probabilities vary with family history. Educational only — not a paternity or medical test.

Kuhusu Child Blood Type Calculator

The Child Blood Type Calculator works out every blood type a child could inherit from their parents, with a probability for each. Choose the mother's and father's ABO group and Rh factor and it builds the full Punnett square for both systems, then combines them into the eight possible types: A+, A−, B+, B−, AB+, AB−, O+ and O−.

ABO inheritance uses three alleles: A and B are co-dominant and O is recessive. That means a parent with type A blood may carry AA or AO, so two type-A parents can still have a type-O child. Rh works the same way with a dominant D allele — two Rh-positive parents can produce an Rh-negative child if both carry the recessive d.

Where a parent's visible blood type allows more than one genotype, the calculator treats each as equally likely, which is the standard textbook assumption. Real probabilities shift with family history and population frequencies, so treat the percentages as a genetics exercise rather than a test result.

Jinsi ya kutumia Child Blood Type Calculator

  1. Select the mother's ABO group: A, B, AB or O.
  2. Select the mother's Rh factor, positive or negative.
  3. Do the same for the father.
  4. Read the list of possible child blood types with their probabilities.
  5. Note the most likely type shown at the top of the results.

Maswali yanayoulizwa mara kwa mara

Yes. If both parents carry an AO genotype, each can pass on the recessive O allele, giving a 25% chance of a type-O child even though neither parent is type O.

Yes, if both parents are Dd carriers. Each can pass the recessive d allele, so about 25% of their children would be Rh negative.

At least one parent must carry an A allele and the other a B allele. An A × B pairing can produce AB, as can any pairing where one parent is AB and the other carries A or B.

Practically never. A type-O parent carries only O alleles, so the child must inherit an O, which rules out AB. The rare exception is the cis-AB variant, an unusual inheritance pattern found in a small number of families.

No. Blood types can sometimes exclude a possible parent, but they can never confirm one — millions of people share each type. Only DNA testing establishes parentage, and this tool is for education only.
