What’s on the Types of Selection poster
A 4-row table: Type · Favours · Effect.
Effect on a trait's distribution curve.
- Directional — One extreme — Mean shifts
- Stabilising — The intermediate — Variance decreases
- Disruptive — Both extremes — Can lead to speciation
- Sexual — Traits attracting mates — Can oppose survival
Human birth weight is the classic stabilising example: both very low and very high weights carry higher risk.
Questions about the Types of Selection poster
- What’s on the Types of Selection poster?
- A 4-row table: Type · Favours · Effect. Effect on a trait's distribution curve. Directional — One extreme — Mean shifts; Stabilising — The intermediate — Variance decreases; Disruptive — Both extremes — Can lead to speciation; Sexual — Traits attracting mates — Can oppose survival. Human birth weight is the classic stabilising example: both very low and very high weights carry higher risk.
- Who is the Types of Selection poster for?
- Types of Selection belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning evolution can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Types of Selection poster?
- Directional shifts the mean. Stabilising narrows it. Disruptive splits it. A wall chart earns its place by being glanceable from where the work is happening, so Types of Selection belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Types of Selection?
- Adaptations, Artificial Selection and Classification sit alongside Types of Selection in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AdaptationsArtificial SelectionClassification
- Is the Types of Selection poster free to download and print?
- Yes. Types of Selection 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 Types of Selection poster print at?
- Types of Selection 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 Types of Selection loses nothing.Printing guide
