Lesson: genes and rsIDs, and what a catalogue actually measures
A ready-to-run genetics lesson for age 16 and up, free to use in any school, college or university. One book everybody owns a copy of: a chapter is a gene, and an rsID names a letter that differs between copies. Then students count those letters in a real catalogue and find the counts measure research attention rather than biology.

Lesson: how to read a pedigree, and where the textbook rule breaks
A free genetics lesson on pedigree analysis. Three clean family trees teach the three inheritance patterns; the fourth is real, and the rule the class just learned gives the wrong answer on it.

Why This Site Has Almost Nothing on Huntington's, ALS or Cystic Fibrosis
Of 660 variants here, Huntington’s has zero, ALS has zero, and cystic fibrosis has one that is not even the gene. That is structural, not laziness — and the reason leads somewhere better than an apology: the study that could not ask who gets Huntington’s asked when instead, and found a target nobody expected.

Lesson: when genetic findings don't apply to other populations
A free lesson on reading data critically, using this site as the dataset. The class computes the same prediction in five populations and measures how wrong it gets — six points for one variant, fifty-two for another. Then we publish our own audit: 72.2% of the variants here were discovered in entirely European samples.

Lesson: p-values, and why genetics uses 0.00000005
A free statistics lesson with one coin per student. The class runs six hundred studies of something that is definitely not happening, gets about thirty-eight discoveries, and works out from there why genetics needs a p-value of 0.00000005 rather than 0.05.

Lesson: lactose tolerance and natural selection
A free genetics lesson on natural selection, with no equipment needed. The class computes a prediction from real allele frequencies, gets a clean answer, and then finds out it is wrong — because the same solution evolved four separate times in the last few thousand years.

Lesson: the PTC taste test, and why the textbook version is wrong
A ready-to-run genetics lesson built on the PTC taste test — free to use in any school, college or university. Forty minutes, one paper strip, and the textbook version of the trait turns out to be wrong in a way that is more interesting than the original.

The Genes Your Parents Didn't Pass On Still Predicted Your Schooling
Three million genomes, 3,952 variants, and a result so strange it changes what the whole field means: the DNA your parents did not pass on still predicts how far you went in school. Here is what the research on studying actually says.

One Gene, Three Answers: What TAS2R38 Decides
The same three coding changes decide whether broccoli tastes bitter, play into how your sinuses fight bacteria, and change whether a child swallows their medicine. One position, three kinds of consequence.
