Allele Frequency Calculator

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.
