Predict Your Child's Blood Type
Formula
Blood type is determined by genetics, specifically the ABO gene and the Rh factor. Each parent passes one ABO allele and one Rh allele to their child, creating various possible combinations.
This calculator shows which blood types are possible for a child based on the parents' known blood types using Mendelian genetics and Punnett square analysis.
Common use cases:
- Family planning and genetics education
- Understanding blood type inheritance
- Medical and paternity considerations
