Binary clone
From Memory Alpha, the free Star Trek reference.
A binary clone is an organism created from the DNA of two individuals. It contains a combination of the DNA from both individuals. Essentially, a binary clone is the artificially produced offspring of two individuals that has been created without using germ cells.
The xenophobic Terra Prime created a binary clone from the DNA of T'Pol and Charles Tucker . (ENT: "Demons", "Terra Prime")
