A hybrid is the end result of mixing two or more different species in the biological process of reproduction.

Because of the common genetic ancestry of most of the species of the Milky Way Galaxy by way of the ancient humanoids, many species are able to interbreed with or without the help of genetic technology. In fact, Humans and Vulcans are quite similar. (TNG: "The Chase"; ENT: "Demons")

There can be unexpected consequences to interspecific relations and as such, it was a researched topic. Starfleet Academy taught Interspecies Protocol and the Ktarian Doctor Mizan was an expert in interspecies mating rituals, known for his "empirical research." (TNG: "Timescape"; VOY: "The Disease") One should note that there can be certain difficulties involved in reproducing between species, even humanoid, for anatomical reasons; for instance, not all species keep their genitals in the same place (Star Trek VI: The Undiscovered Country), or incompatible number of required genitals (DIS: "Choose Your Pain"), or the embryo will not survive to term due to genetic or physical reasons, such as life-threatening birth defects or dangers to the mother during birthing which may require caesarean section or fetal transport to save one or both. (VOY: "Deadlock")

In some cultures, children who are born as a result of interspecific relations are rejected by the society of both races. For example, Bajoran / Cardassian hybrids were often rejected by both Bajorans and Cardassians. (DS9: "Indiscretion", "Return to Grace") Klingons referred to hybrids derogatorily as "mongrels". (VOY: "Barge of the Dead", "Prophecy")

Examples of interspecific reproduction Edit

Betazoid Edit

Caitian Edit

Cardassian Edit

Seska also seemed to think Cardassian / Human cross breeding was possible, as she attempted to have Chakotay's child.
Gilora Rejal apparently made the same assumption when she expressed interest in Miles O'Brien.

Human Edit

In an initial story outline of TOS: "Charlie X", Charles Evans was referred to as a Human/Ferndok hybrid, since his mother was a Ferndok (a species which, during the episode's development, was later renamed Thasian).
According to the original script of TOS: "Who Mourns for Adonais?", interbreeding between Humans and the Greek god species is also possible, as Carolyn Palamas got impregnated by Apollo. However, this was cut from the actual episode, but was later used in the Star Trek: New Visions comic Of Woman Born. The 31st century time-traveler Daniels stated he was "more or less" Human, meaning he could be a possible hybrid.

Klingon Edit

Ocampa Edit

Romulan Edit

In the novel The Ashes of Eden, Kirk discovered the colony world of Chal, a planet briefly colonized by the Romulans and Klingons during an alliance, populated by genetically-engineered Klingon-Romulan hybrids.

Talaxian Edit

Trill Edit

Vulcan Edit

In the first draft script of Star Trek III: The Search for Spock, another Vulcan/Human hybrid, called Galt, was to have been introduced.
It may be assumed that a Vulcan and Romulan would be able to breed due to their common ancestry. The production notes from Star Trek: Enterprise state that the creators were planning to reveal T'Pol as a Romulan/Vulcan hybrid if the series had continued. In this case, her baby with Trip would be 1/4 Romulan, 1/4 Vulcan and 1/2 Human. Saavik was intended to be half-Romulan in Star Trek II: The Wrath of Khan, but a scene establishing this was cut.
Ronald D. Moore opined that as a changeling, Odo could not reproduce with solids. (AOL chat, 1997)
