1. What is Blood Type Probability?

Blood type probability calculates the likelihood of offspring inheriting specific blood types based on parental genotypes using Punnett squares. The probability formula is:

Where \( P \) is probability (dimensionless), \( F \) is favorable outcomes (dimensionless), and \( T \) is total possible outcomes (dimensionless).

2. How Does the Calculator Work?

The calculator uses Mendelian genetics principles:

• A and B are codominant alleles
• O is recessive to both A and B
• Each parent contributes one allele

Example: Parent with AO genotype can pass either A or O allele (50% chance each).

3. Importance of Blood Type Prediction

Details: Predicting blood types is important for blood transfusion compatibility, pregnancy management (Rh incompatibility), and understanding inheritance patterns.

4. Using the Calculator

Tips: Select the genotype (not phenotype) for each parent. Remember that AO and AA both result in blood type A phenotype, but have different inheritance patterns.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between genotype and phenotype?
A: Genotype is the genetic makeup (e.g., AO), while phenotype is the observable trait (e.g., blood type A).

Q2: Can two parents with type A have a child with type O?
A: Yes, if both parents are heterozygous (AO genotype), there's a 25% chance of an OO child.

Q3: What's the rarest blood type?
A: AB negative is the rarest in most populations, followed by B negative.

Q4: How accurate are these predictions?
A: This assumes simple Mendelian inheritance. Rare mutations or Bombay phenotype can affect results.

Q5: Can this calculator predict Rh factor?
A: No, this calculator only predicts ABO blood types. Rh factor follows similar but separate inheritance.
