💡use a noun (generosity), not an adjective (generous), with 'trait'.

Common in biology and medicine. Distinguish from sense 1: sense 2 is about physical or biological features (eye color, disease risk), not personality. For genetic inheritance, trait is typically paired with dominant, recessive, inherited, or genetic.
