Pedigrees are a widely used tool in medicine, research, and teaching. In the classroom, pedigrees are a helpful tool for students to learn about genetics and the various ways in which genetic traits can pass through families. Traditionally, what most people have learned about pedigrees in school is that squares are for males, circles are for females, and lines indicate connections between parents and children across generations. Family structures and personal identities are wide ranging and so, for many people, this nomenclature will fall short. For example, people who were adopted or conceived by donor sperm may grapple with how to accurately portray their family relationships. And people whose gender identity does not align with their sex assigned at birth may find these symbols inadequate. How can educators create an environment that is welcoming and inclusive for all students, while still being able to clearly convey genetic concepts?
