What’s on the Hardy-Weinberg poster
The rule, 3 worked examples, and the mistake everyone makes.
- Allele and genotype frequencies stay constant across generations under specific condi…
- p + q = 1 · p² + 2pq + q² = 1
- q² = 0.04 (affected) = q = 0.2, p = 0.8
- Carrier frequency = 2pq = 2(0.8)(0.2) = 0.32
- Homozygous dominant = p² = 0.64
- Common mistake: Applying it without checking assumptions → Checking all five
Deviation from equilibrium is the useful result: it indicates selection, drift, migration or non-random mating.

- Who is the Hardy-Weinberg poster for?
- Hardy-Weinberg belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning genetics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Hardy-Weinberg poster?
- It describes a population NOT evolving. Deviation from it is evidence that something is happening. A wall chart earns its place by being glanceable from where the work is happening, so Hardy-Weinberg belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Hardy-Weinberg?
- CRISPR-Cas9, DNA Sequencing and Epigenetics sit alongside Hardy-Weinberg in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CRISPR-Cas9DNA SequencingEpigenetics
- Is the Hardy-Weinberg poster free to download and print?
- Yes. Hardy-Weinberg downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Hardy-Weinberg poster print at?
- Hardy-Weinberg is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Hardy-Weinberg loses nothing.Printing guide
