Elizabeth, a binary clone of T'Pol and Trip Tucker
A binary clone was an organism created from the combination of DNA from two individuals. Essentially, a binary clone was the artificially produced offspring of two individuals that had been created without using germ cells.
The xenophobic group known as Terra Prime created a binary clone from Starfleet Commanders Charles Tucker and T'Pol, intending to use this infant, Elizabeth, as a rallying point for their anti-alien views. (ENT: "Demons", "Terra Prime")
