An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.


Narration



"Inherited" is a word we use to describe traits that are passed by genetics from parents to child. It is often confused with the word "familial", which sometimes people use to mean the same thing. But it's important to recall that familial traits can be either acquired or inherited and can be caused by shared environment. When geneticists use the word "inherited", it's limited to the vertical transmission of traits attributable to genes.
