Blood Type Calculator Baby ABO

Curious about your baby's possible blood type? Blood Type Calculator is a fun educational tool that predicts a child's blood type based on simple Mendelian genetics — the same Punnett-square logic taught in biology class.

Select each parent's ABO blood type (A, B, O, AB) and Rh factor (Rh+ or Rh−), then tap Calculate. The app instantly shows every possible blood type a child could have, along with the probability for each.

▶ Key Features

• ABO Blood Type Prediction
Enter two parents' ABO blood types to see all possible combinations for their child. Each result is shown with a clear percentage and a visual progress bar.

• Rh Factor Estimation
Select each parent's Rh factor to see the likelihood of a child being Rh+ or Rh−.

• Blood Type Reference Chart
An educational reference table showing how different blood types relate to each other — handy for students and the simply curious.

• World Blood Type Distribution
Explore global blood type statistics from O+ (the most common) to AB− (the rarest).

▶ How It Works

Blood type inheritance follows Mendelian genetics. Each parent passes one allele to their child.

Examples:
- Parent A + Parent B → Child can be A, B, AB, or O
- Parent O + Parent O → Child is always O
- Parent AB + Parent O → Child can be A or B
