Genetic engineering

== Dominion ==
The [[Founder]]s of the [[Dominion]] performed extensive genetic modifications on their two servant races, the [[Jem'Hadar]] and the [[Vorta]], in order for them to better serve their roles and to ingrain a fanatical devotion to the Founders. ({{DS9|The Abandoned|Ties of Blood and Water}}) As a result of these modifications, neither species reproduced in the traditional biological sense. ({{DS9|To the Death}})

According to Vorta legend, they were originally ape-like creatures who were gifted sentience by the Founders after they helped a Changeling escape pursuit. ({{DS9|Treachery, Faith and the Great River}}) 

{{bginfo|It is unknown whether the Jem'Hadar had any such ancestral species.}}

The Dominion also genetically engineered [[biological weapon]]s, such as the [[Teplan blight|blight]] they unleashed against the people of the [[Teplan system]]. ({{DS9|The Quickening}})
