Epistasis Calculator
The Epistasis Calculator is a scientifically validated tool designed to quantify genetic interactions between two loci. It allows researchers, students, and geneticists to determine whether the combined effect of two mutations is additive, synergistic, or antagonistic, following established principles in population genetics and evolutionary biology.
By using peer-reviewed epistasis equations, this calculator provides a reliable way to analyze non-additive genetic effects that play a critical role in evolution, disease genetics, and complex trait analysis.

Enter the fitness values for each genotype. The calculator will compute the epistasis value and interpret the genetic interaction.
📘 About the Epistasis Calculator
The Epistasis Calculator measures how genetic variants interact to influence biological traits. Epistasis occurs when the combined effect of two genes differs from what would be expected if their effects were purely additive.
This phenomenon is central to modern genetics because most traits — including disease susceptibility, agricultural yield, and evolutionary fitness — are influenced by interactions among multiple genes rather than single loci acting independently.
By providing a numerical epistasis value, this tool allows users to move beyond qualitative descriptions and apply rigorous quantitative analysis.
🎯 Purpose of This Tool
The main purpose of the Epistasis Calculator is to provide a simple yet scientifically sound way to evaluate gene–gene interactions.
- Quantify non-additive genetic effects
- Support evolutionary and population genetics studies
- Assist in complex trait and disease research
- Enhance educational understanding of epistasis
📊 Importance of Epistasis in Genetics
Epistasis plays a fundamental role in shaping evolutionary trajectories. It influences how populations respond to natural selection, how genetic diversity is maintained, and why some evolutionary paths are constrained.
In medical genetics, epistasis helps explain why individuals with similar mutations may show different disease outcomes. In agriculture, it affects crop yield, stress resistance, and breeding strategies.
Ignoring epistasis can lead to oversimplified models and inaccurate predictions, making tools like this calculator essential for robust genetic analysis.
