Is tetra the first cloned monkey still alive?

Tetra, the first cloned monkey, was not the first cloned monkey. The first cloned monkey was named ANDi, short for "Advanced Neural Dynamics" and created in 2000.

Tetra, cloned in 2007, was the first rhesus macaque monkey cloned using the somatic cell nuclear transfer (SCNT) method, which is the same method used to clone Dolly the sheep.

As for whether Tetra is still alive, there's no publicly available information about her current status. Records of cloned animals are often not maintained publicly, especially in research settings.
