FIGURE 2.

Experts and novices use different representations when asked to draw a gene. (A) Drawings in response to the prompt were coded according to an emergent scheme. The y-axis represents the percentage of participants who used a particular representation, as several participants used more than one category of representation in their drawing (n = 18 experts, n = 23 students). **p < 0.01; ***p < 0.001. (B) The most common representation created by experts was a box-and-line diagram, while students most often drew chromosomes.
