## Overview

The Blood Type Calculator is a simple, science-based tool that determines the potential ABO and Rh blood types of a child based on the genetic profiles of both parents.

## Inputs

- **Parent 1 Blood Type** (select)
- **Parent 1 Rh Factor** (select)
- **Parent 2 Blood Type** (select)
- **Parent 2 Rh Factor** (select)

## When to use

- When you want to understand the genetic possibilities of blood inheritance.
- When exploring how ABO and Rh factors combine from two biological parents.
- When you need a quick reference for educational purposes regarding blood type genetics.

## How it works

- Select the ABO blood type and Rh factor for Parent 1.
- Select the ABO blood type and Rh factor for Parent 2.
- Click calculate to view the list of all possible blood type combinations for their offspring.

## Use cases

- Biology students studying Mendelian genetics and inheritance patterns.
- Parents curious about the genetic possibilities of their child's blood type.
- Healthcare educators explaining blood type compatibility to patients.

## Frequently asked questions

### Is this calculator medically diagnostic?

No, this tool is for educational and informational purposes only and should not be used for medical diagnosis or paternity testing.

### What does the Rh factor represent?

The Rh factor is a protein found on the surface of red blood cells; being Rh positive means you have the protein, while negative means you do not.

### Can two O-type parents have an A-type child?

No, two parents with type O blood can only produce children with type O blood.

### Does this tool account for rare blood types?

This calculator focuses on the standard ABO and Rh systems and does not account for rare antigens or mutations.

### How accurate are these predictions?

The results are based on standard Mendelian inheritance patterns for the ABO and Rh blood group systems.

F is dimensionless and lies in \[0, 1\]; IV bioavailability is by definition 1, while oral F < 1 reflects incomplete absorption and/or first-pass metabolism. AUC can be in any consistent unit (e.g. mg·h/L) since it cancels out of the ratio. Valid only for linear pharmacokinetics, the same drug molecule, and doses within the linear range.
