Type: Interactive simulation sim-id: polygenic-inheritance
Library: p5.js
Status: Specified

An interactive simulation where users adjust the number of contributing loci (1 to 20) using a slider. The display shows a histogram of phenotypic values in a simulated F2 population, demonstrating how increasing the number of loci transforms the distribution from discrete classes to a smooth bell curve. A second slider adds environmental noise to show how environment further smooths the distribution. The current number of phenotypic classes and distribution statistics are displayed.
