What’s on the Beyond Mendel poster
A 6-row table: Pattern · Means · Example.
Inheritance patterns beyond simple dominance.
- Incomplete dominance — Heterozygote is intermediate — Pink snapdragons
- Codominance — Both alleles fully expressed — AB blood group
- Multiple alleles — More than two in the population — ABO blood groups
- Polygenic — Many genes, continuous variation — Height, skin colour
- Epistasis — One gene masks another — Coat colour in mice
- Sex linkage — Gene on a sex chromosome — Haemophilia, colour blindness
X-linked recessive conditions affect males far more often: males have only one X, so there is no second allele to mask it.

- Who is the Beyond Mendel poster for?
- Beyond Mendel 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 Beyond Mendel poster?
- Most real traits are not simple. These are the standard exceptions. A wall chart earns its place by being glanceable from where the work is happening, so Beyond Mendel belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Beyond Mendel?
- CRISPR-Cas9, DNA Sequencing and Epigenetics sit alongside Beyond Mendel 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 Beyond Mendel poster free to download and print?
- Yes. Beyond Mendel 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 Beyond Mendel poster print at?
- Beyond Mendel 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 Beyond Mendel loses nothing.Printing guide
