What is a Blood Type Punnett Square Calculator?
A Blood Type Punnett Square Calculator predicts potential blood types of offspring based on parental genotypes. Using Mendelian genetics principles, it visualizes possible combinations of parental alleles (A, B, O) that determine ABO blood types. This tool helps understand inheritance patterns, showing statistical probabilities of children inheriting specific blood types. While simplified, it demonstrates basic genetic inheritance concepts used in biology and medicine for blood type prediction.

Genetic Formula
Blood type inheritance follows the formula:
Child's genotype = (Allele from Parent 1) + (Allele from Parent 2)
Phenotype determination:
- AA/AO = A type
- BB/BO = B type
- AB = AB type
- OO = O type
Advantages and Disadvantages
Advantages
1. Educational Value: Provides clear visualization of genetic inheritance patterns
2. Predictive Tool: Estimates probable blood type outcomes
3. Medical Planning: Helps anticipate possible blood types for transfusions
4. Simple Interface: Makes complex genetics accessible to non-experts
5. Cost-effective: Free alternative to genetic testing for basic predictions
Disadvantages
1. Oversimplification: Ignores Rh factor and other blood group systems
2. Probability Limitations: Shows possibilities not certainties
3. Genetic Complexity: Doesn't account for rare mutations or cis-AB phenomenon
4. Parental Assumptions: Requires exact knowledge of parental genotypes
5. No Serological Factors: Doesn't consider antigen expression variations
6. Ethnic Variations: Doesn't account for population-specific allele frequencies
7. Medical Limitations: Should not be used for critical medical decisions
