Definition
Nonhereditary describes a condition, trait, or characteristic that is *not* passed down from parents to offspring through their genes. Think of it as a limited-edition skin in a video game 🎮; it looks cool, but it doesn't automatically appear on your sibling's account. It arises from environmental factors, lifestyle choices, or random events during a person's lifetime. This contrasts with hereditary traits, which are genetically transmitted from one generation to the next. It means the trait stops with the individual.
