A scientist who studies genes and heredity—how traits get passed down from parents to children.
From 'genetics' (Greek 'genesis' meaning origin) plus the agent suffix '-ist'. The field of genetics was formalized by Gregor Mendel's pea plant experiments in the 1860s.
Geneticists discovered that DNA is like a instruction manual written in just four letters (A, T, G, C), yet these four letters contain all the information needed to build every living thing—including you!
Profession historically dominated by men; women pioneers (Barbara McClintock, Rosalind Franklin) often erased or under-credited in foundational genetic research.
Use without assumption of gender; when historical, credit women's contributions explicitly.
Barbara McClintock's discovery of genetic transposition was initially dismissed; Rosalind Franklin's X-ray crystallography was central to understanding DNA structure but poorly attributed.
