The branch of science that studies genes, heredity, and how traits are passed from parents to offspring.
From *genetic* (about origins, birth) + *-ics* (science of), influenced by Greek *genetikos* “fit for producing.” Coined in the early 20th century as scientists began to understand heredity in a systematic way. It quickly became central to biology and medicine.
Genetics shows that tiny changes in DNA can shape everything from height to disease risk — but environment still has huge power. Identical twins share nearly all their genes, yet their lives and even their bodies can diverge dramatically, proving genes are only part of the script.
Genetics research has sometimes been misused to claim innate gender differences in intelligence, temperament, or aptitude, often to justify exclusion of women from education or professions. Many such claims were methodologically flawed or biased.
Be precise about what genetics can and cannot explain, and avoid deterministic claims about gendered abilities or behavior. Emphasize the role of environment, culture, and individual variation.
Highlight contributions by women geneticists and biologists, whose work often corrected earlier biased interpretations.
