About Three Level Genetics

The person behind it

I'm Lukas, a data analyst from Belgium with a deep enthusiasm for genetics and learning. I built Three Level Genetics because I wanted a resource that doesn't force you to choose between "dumbed down" and "impenetrably technical" — the kind of layered explanation I wished existed when I was trying to understand the field myself.

When I'm not working with data, I'm usually reading about molecular biology, building side projects, or figuring out how to explain something complicated in plain language.

The three-level approach

Every module on this site covers the same concepts at three levels, described here as perspectives rather than ability tiers:

• Everyday analogies (age 10) — Concrete stories and real-world metaphors. DNA as a recipe book, chromosomes as chapters. No technical vocabulary required.
• High-school biology (age 15) — Proper terminology, clearly introduced. Named processes, ratios, and the experiments that confirmed them. Exam-ready but not dense.
• College depth (age 20) — Mechanisms, not just facts. For each named molecule or pathway, the site explains what it acts on, what the molecular event is, and what the consequence is. Caveats and open questions are included.

Switching between levels is instant — the same content, reformatted around your background. Glossary tooltips, gene case studies, and interactive exercises all follow your level choice.

How content is reviewed

Every module goes through a structured fact-check before being published. Claims in the age-20 (college depth) content are individually verified against Wikipedia as a minimum baseline, using a documented review workflow: each claim is checked by a separate reviewer agent, flagged if imprecise or incorrect, and corrected before the module is marked as verified.

This doesn't make the content infallible — genetics moves fast, and some topics involve genuine scientific debate. Where that's the case, the text says so explicitly rather than presenting one view as settled fact.

What's on the site

• Nine curriculum modules from DNA basics through RNA, CRISPR, genome testing, population genetics, human evolution, and bioethics
• Gene case studies: BRCA, sickle-cell haemoglobin (HBB), and lactase persistence (LCT)
• Curiosity stories — short reads on surprising genetics topics, from cat coat patterns to PCR during COVID-19
• Genetics news — recent headlines from journals and publishers, each with a link to the original report and a three-level explanation of the science (open the feed)
• A glossary of ~100 genetics terms, all level-aware
• Interactive simulators: meiosis, pedigrees, Hardy–Weinberg equilibrium, and more
• A discovery timeline from Mendel to CRISPR therapies

Genetics news

The Genetics news section is a curated feed of recent genetics headlines. Each item links to the original journal or publisher report and includes an original explanation written at all three reading levels — the same everyday analogies, high-school biology, and college depth as the rest of the site.

Click any headline to expand the full explanation, key facts, and links to related curriculum modules. News items reflect what was reported at the time of publication; preclinical results are labelled as such, and open questions are stated explicitly rather than presented as settled fact.

Feedback and corrections

Found something wrong? The "Something wrong?" button in the app opens a feedback form that goes directly to me. You can also email contact@threelevelgenetics.com.

Three Level Genetics is a personal project, not a funded institution — but I take accuracy seriously. Corrections are always welcome and acted on.
