Skin

To say that Nana was bred for pleasure is not exactly accurate. A paramour she, indeed, became, but hers was an altruistic genesis (in a prototypical sense), a tool for tissue regeneration, a renewable stem cell resource for graft-quality skin. But, like so many donor drones engineered in the early days of Synthegenetics, some tampering had occurred, creating a non-fatal exception, in Nana's case, which ordinarily never would have come to term. Yet, due to a phenomenon dubbed "spontaneous parturition" whereby material deemed appropriate for a single characteristic abruptly takes on many, Nana's altered cells proceeded to divide. Left unchecked (and given a suitable habitat) the end result was a viable human being-embryo onto foetus onto bouncing baby boy. Or girl. Or Nana Wolffm ller-whose gender classification was logged as "ambiguous" because, anatomically speaking, her genitalia proved... unique.
