Portraits Derived From the DNA in Hair and Gum

Some of the subjects have shared, what looks like, their dna on Github[0]. Since this is art, I wonder what part the modeling software is doing, and what part she is doing. It's too bad she is not open-sourcing it, unless she likes you (friendware [1]).
