No. Rh-negative means both alleles are negative (dd), so both parents can only pass on negative alleles. The child will always be Rh-negative.
This calculator provides probabilities based on standard Mendelian inheritance. In rare cases, mutations or other genetic factors may result in unexpected blood types. For definitive results, genetic testing is required.
The rarest ABO-Rh combination is AB-negative, found in less than 1% of the population globally. O-negative is also relatively rare but is the universal donor type, making it highly valuable for blood transfusions.
