Interactive Demo
Genetic Linkage & Recombination Demo
Genetic Linkage & Recombination Demo is a free, interactive learning demo from the Introductory Biology course on Lykke. It helps you build intuition for Recombination Frequency, Centimorgans (cM), Three-point Cross, SNP Mapping. Play with it directly in your browser — it features 2 sliders and a live visual canvas. This demo lives in the “Genetic Mapping and Linkage” section of the course.

How to use this demo
- Drag the “Physical Distance (Map Units / cM)” slider to change the inputs and watch the result update live.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Recombination Frequency
- Centimorgans (cM)
- Three-point Cross
- SNP Mapping
- Yeast Tetrad Analysis
Frequently asked questions
What does the Genetic Linkage & Recombination Demo demo do?
Genetic Linkage & Recombination Demo The Linkage Mapping Sandbox Adjust gene distance to see how recombination frequency (RF) behaves. Physical Distance (Map Units / cM) Linked (1 cM) Unlinked (150 cM) Map Distance 20.0 cM Observed Recombination (RF) 16.5% Gene A Gene B Crossover Event Genes are close together; they are likely to be inherited as a single unit. Genetic Linkage & Recombination Demo lets you explore this hands-on instead of only reading about it.
What Introductory Biology concept does Genetic Linkage & Recombination Demo teach?
Advanced genetics focusing on gene linkage, recombination frequencies, and mapping techniques. It focuses on Recombination Frequency, Centimorgans (cM), Three-point Cross, SNP Mapping, Yeast Tetrad Analysis from the “Genetic Mapping and Linkage” section.
What can I control in Genetic Linkage & Recombination Demo?
The “Physical Distance (Map Units / cM)” slider change the key inputs. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Genetic Linkage & Recombination Demo fit into the Introductory Biology course?
7.016 Introductory Biology provides a comprehensive exploration of the molecular and cellular foundations of life, integrating biochemistry, genetics, and molecular biology. The course emphasizes the structure and regul… This demo is the interactive piece for the “Genetic Mapping and Linkage” section.

What will I understand better after using Genetic Linkage & Recombination Demo?
You'll build intuition for Recombination Frequency, Centimorgans (cM), Three-point Cross, SNP Mapping, Yeast Tetrad Analysis — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Introductory Biology alone.
