# Allele Frequency Calculator

 Calculate allele frequencies from genotype counts in a population. Use this free browser-based allele frequency calculator from XTRAW Tools.

 **Allele Frequency Calculator** helps you calculate allele frequencies from genotype counts in a population. Use this free browser-based calculator from XTRAW Tools to compare inputs, estimate results, and plan your next step.

## How to Use the Allele Frequency Calculator

1. Enter the required calculator inputs shown in the form.
2. Review the biology, genetics, lab, microscope, asphalt, paver, sand, or base-material assumptions.
3. Run the calculator, then adjust one input at a time to compare scenarios or check your estimate.

## What This Calculator Helps With

Calculate allele frequencies from genotype counts in a population. It is designed for students, teachers, biology learners, genetics users, lab users, healthcare reference users, STEM tutors, and anyone working with biology or lab formulas who want a fast browser-based estimate before relying on a textbook, lab software, supplier chart, contractor estimate, science reference, professional source, or specialist.

- Homozygous Dominant (AA) count: 36
- Heterozygous (Aa) count: 48
- Homozygous Recessive (aa) count: 16

## Common Uses

People use this calculator when they need a quick way to estimate allele frequency, genotype probability, phenotype probability, or Hardy-Weinberg expectations.

- **Math Solving:** Solve biology, genetics, microscopy, biochemistry, construction, or material-estimating equations from entered values.
- **Measurement:** Measure sequence composition, allele frequency, enzyme activity, microscope magnification, cell density, paving volume, paver count, or base material quantities.
- **Project Planning:** Plan lab estimates, STEM assignments, patio work, hardscape projects, paving jobs, biology study workflows, or material orders.

## Formula or Method

p = (2×AA + Aa) / (2×total); q = 1 − p

## Example

**Example inputs:** Homozygous Dominant (AA) count: 36; Heterozygous (Aa) count: 48; Homozygous Recessive (aa) count: 16

**Example result:** Using the default counts, p = 0.60, q = 0.40, and total individuals = 100.
