How can i remember this definition of heredity? the transmission of genetic traits from parents to offspring

This is how I would remember it:

Think of a train with two stops. It stops at the parent stop, loads the genetic traits in the caboose, then transmits them to the next stop, the offspring. The train chugs along between parent and offspring, it's only purpose to pass along the traits to the next stop, or offspring. The train's name is Here, Dity

Hope this helped! :)
