When a person receives an organ transplant, they are taking in the DNA of another person ....merged and integrated into their own DNA. That doesn't suddenly change their personhood. But they do often experience life changes like having sudden food preferences or music preferences, etc, of the donor. But you could say those doctors are playing God as well. Just putting that out there...This is not good though, it’s like playing God. I was against when they first started cloning animals, never thought humans were cloned as it is forbidden.
