Models

This figure illustrates a typical non-linear biological response, where a trait like body weight, enzyme activity, or gene expression changes with genotype or input dose. The S-shaped sigmoid curve models threshold behavior, where initial changes are minimal, followed by a sharp transition zone, and finally a plateau phase where further increases in input (e.g., gene copy number or substrate concentration) produce little or no additional response. Such curves are common in genetics (e.g., dominance effects), pharmacology (dose-response), and ecology (population saturation).

Non-Linear Models – Biology Is Never Straight

Biological systems are beautifully complex — and this complexity often shows up in data that doesn’t follow a straight line. […]
