Genetics
The Holy Father, from Pope says humans amount to more than their DNA:

The people of our time... sensitised by the terrible vicissitudes that have covered the 20th century and the very beginning of this one in mourning, are able to understand that man's dignity is not identified with his DNA genes and that it does not diminish with the eventual presence of physical differences or genetic defects....

The principle of "non-discrimination" in virtue of physical or genetic factors has entered profoundly in consciences and is enunciated formally in the charters on the rights of man....

This principle has its most authentic foundation in the very dignity of every human being by the fact of having been created in the image and likeness of God.
