Genetic tools

Fast, transparent utilities for teaching, planning, and exploratory work. Results are informational and never a clinical interpretation.

Inheritance estimator

Estimate simple Mendelian offspring probabilities from two parental genotypes.

Parent one Parent two 25% AA · 50% Aa · 25% aa

Example · Aa × Aa

DNA mass calculator

Convert double-stranded DNA length and molar amount into approximate mass.

Length (bp)Amount (pmol)19.8 µg

Example · 3,000 bp · 10 pmol

Sequence translator

Translate a DNA sequence into one-letter amino-acid notation using the standard code.

DNA sequenceMA*

Example · ATGGCTTAA

Motif counter

Count exact, overlapping sequence motifs in a DNA string.

DNA sequenceMotif3 matches

Example · GAATTC in a sequence

Generation interval

Calculate the average interval between recorded birth years.

Birth years28.5 years

Example · 1984 · 2012 · 2041

Sample planner

Estimate a baseline sample size for a proportion at a chosen confidence and margin.

ConfidenceMargin (%)385 samples

Example · 95% · ±5%

Scope of use

These calculators simplify established formulas. They do not diagnose, identify biological relationships, or replace laboratory validation, genetic counselling, or professional review.
