The term 'ROOTED BY HEREDITY' can be summarized by the 6-letter word 'INBRED'. INBRED is a term used to describe an organism that has been bred from closely related parents, resulting in a higher chance of inheriting similar characteristics. This term is often used to describe plants and animals, as well as humans, and is rooted in the concept of heredity, or the passing of traits from one generation to the next.
