Allometric vs isometric scaling on a graph: In a log-log plot, allometric scaling is represented by a power function, resulting in a straight line with a slope that differs from 1. Here, the trait scales differently than body size, being either disproportionately smaller (slope < 1) or larger (slope > 1). Isometric scaling, on the other hand, shows a line with a slope of 1, indicating that the trait scales in direct proportion to body size, retaining its relative proportions.
