Heredity Heredity is the passing on of characteristics from parents to offspring. All living things pass on traits from one generation to the next.
All children inherit traits from their parents.
A boy may be blond and blue-eyed like his mother. A girl may have curly hair like her father , and a nose like her grandmother. Sometimes traits can be traced to more distant relatives. The traits that one inherits from parents by way of the sperm and egg are called biological inheritance. All inherited traits may not stay the same throughout a lifetime.
