Definition
Nonheritable means a trait or characteristic that *cannot* be passed down genetically from parents to offspring. Think of it like a high score in a video game🎮; you earn it, but it doesn't automatically transfer to your kids. This is because it's not coded into your DNA. It is usually due to environmental factors, lifestyle choices, or random events that occur during one's lifetime. It stands in contrast to heritable traits, which *are* genetically transmitted.
