June 3, 2014 - IAS faculty member Becca Price co-authored an article, “The Dominance Concept Inventory,” in CBE-Life Science Education. The article describes a tool that measures what students understand about the relationships between different pairs of gene types. A common example of a dominant gene is the eye color gene for brown eyes – someone who inherits both brown and blue versions of the eye color gene has brown eyes. Students learning genetics often conflate dominance with being common or with being selectively advantageous. The tool Price and her colleagues developed helps instructors determine whether their students understand the differences among dominance, commonness, and advantage.
