What’s on the Nature & Nurture poster
A definition and 6 facts worth remembering.
Behaviour genetics estimates the proportion of variation in a trait attributable to genetic differences within a population — not the proportion of any individual's trait that is genetic.
- Heritability is about variation in a population, not about an individual.
- Identical twins share ~100% of DNA; fraternal ~50%.
- Most psychological traits show moderate heritability, roughly 40–60%.
- Shared environment effects are often smaller than expected.
- Gene-environment correlation: genes influence the environments people select.
- Epigenetics: environment alters gene expression.
- Heritability — population-level
- Most traits — ~40–60%
- Interaction — constant
- High heritability of height does not mean nutrition is irrelevant — it means, in this…
Heritability is not fixed: it rises when environments are equalised, because environmental variation has been removed.

- Who is the Nature & Nurture poster for?
- Nature & Nurture belongs to the Psychology section rather than to a school year, because life science is not something one grade owns. Anyone learning developmental can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Nature & Nurture poster?
- It is not a competition. Almost every trait is both, and they interact. A wall chart earns its place by being glanceable from where the work is happening, so Nature & Nurture belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Nature & Nurture?
- Adolescence, Cognitive Ageing and Attachment sit alongside Nature & Nurture in the Psychology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AdolescenceCognitive AgeingAttachment
- Is the Nature & Nurture poster free to download and print?
- Yes. Nature & Nurture downloads as a free PDF with no account, no email and no watermark, like everything else in the Psychology 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 Nature & Nurture poster print at?
- Nature & Nurture 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 Nature & Nurture loses nothing.Printing guide
