Blood Type Calculator
Predict possible blood types with Rh factor probabilities
How Blood Type Inheritance Works
Blood types are determined by combinations of ABO alleles (A, B, O) and Rh factor (positive/negative) inherited from both parents. The A and B alleles are co-dominant, while O is recessive. Rh+ is dominant over Rh-.

Blood Type Calculator
A blood type calculator is a scientific tool designed for calculating blood type probabilities for offspring based on parental blood types. Using Mendelian genetics, this blood calculator type helps predict possible ABO blood groups and Rh factors.
What is a Blood Type Calculator?
A blood type calculator allows users to enter the blood types and Rh factors of both parents. It then calculates the likelihood of all possible blood types for their children. This tool simplifies complex genetic principles into easy-to-understand probabilities, making calculating blood type straightforward for educational and family planning purposes.
How the Blood Type Calculator Works
- ABO Blood Group System: Codominance of A and B alleles; O is recessive.
- Rh Factor System: Rh+ is dominant; Rh- is recessive.
- Each parent contributes one allele for ABO and one for Rh factor.
- Combinations generate probabilities for 16 possible outcomes.
Using the Calculator
- Select the blood type and Rh factor for Parent 1.
- Select the blood type and Rh factor for Parent 2.
- Click the “Calculate Blood Type Probabilities” button to see results.
- Review probability percentages and visual probability bars.
Common Blood Type Probabilities
Here is a quick reference table for common parental blood type combinations:
| Parent 1 | Parent 2 | Possible Child Blood Types | Probability Example |
|---|---|---|---|
| A+ | A+ | A+, O+ | A+ (75%), O+ (25%) |
| AB+ | O- | A+, A-, B+, B- | Each 25% |
| B- | O- | B-, O- | B- (50%), O- (50%) |
| A+ | B+ | A+, B+, AB+, O+ | Each 25% |

Limitations
While this blood calculator type provides accurate probability estimates based on genetics, real-world variations such as rare alleles, mixed heritage, or medical factors can affect outcomes. The tool is intended for educational purposes and should not replace professional medical advice.
