Interspecies reproduction
From Memory Alpha, the free Star Trek reference.
Because of the common genetic ancestry of most of the races 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 even humanoid species for certain, anatomical reasons. For instance, not all species keep their genitals in the same place. (Star Trek VI: The Undiscovered Country)
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 are often rejected by both Bajorans and Cardassians. (DS9: "Indiscretion", "Return to Grace")

[edit] Examples of interspecific reproduction
[edit] Betazoid
- Betazoid/Human (Deanna Troi, Kestra Troi)
- Betazoid/Tavnian (Lwaxana Troi's and Jeyal's child) (DS9: "The Muse")
[edit] Cardassian
- Cardassian/Bajoran (Mika and Dukat's child, and Tora Ziyal) (DS9: "Covenant")
- Cardassian/Kazon (Seska and Culluh's child) (VOY: "Basics, Part I", "Basics, Part II")
- Seska also seemed to think Cardassian/Human cross breeding was possible, as she attempted to have Chakotay's child.
[edit] Human
- Human/Boraalan (Nikolai Rozhenko and Dobara's child) (TNG: "Homeward")
- Human/Betazoid (Deanna Troi, Kestra Troi)
- Human/Cardassian (implied above)
- Human/Daliwakan (The Gigolo) (VOY: "The Cloud") (only a hologram, but presumably possible)
- Human/Ikaaran
- Human/Klingon (K'Ehleyr (medical help was needed (TNG: "The Emissary"), B'Elanna Torres, Alexander Rozhenko, Miral Paris)
- Human/Ktarian (Naomi Wildman) (VOY: "Deadlock")
- Human/Napean (Daniel Kwan) (TNG: "Eye of the Beholder")
- Human/Ocampa (Linnis Paris, Andrew Kim) (VOY: "Before and After")
- Human/Romulan (Sela, Simon Tarses)
- Human/Skagaran (Bethany) (ENT: "North Star")
- Human/Trill (Yedrin Dax) (DS9: "Children of Time")
- Human/Vulcan (Spock, Elizabeth, Lorian)
- Human/Xyrillian (Trip Tucker's pregnancy; it should be noted, however, that he was more of a carrier than an actual, biological parent) (ENT: "Unexpected")
- Q has implied that a Human/Q hybrid is possible (TNG: "True Q"; VOY: "The Q and the Grey")
- It may be assumed that the Q could breed with any species because of their godlike abilities.
[edit] Klingon
- Klingon/Betazoid/Human (Shannara and Eric-Christopher, alternate timeline children of Worf and Deanna Troi) (TNG: "Parallels")
- Klingon/Human (K'Ehleyr (medical help was needed), B'Elanna Torres, Alexander Rozhenko, Miral Paris)
- Klingon/Trill (not possible without medical help) (DS9: "Tears of the Prophets")
- Klingon/Romulan (Ba'el and several other prisoners in the Carraya IV colony) (TNG: "Birthright, Part I")
[edit] Talaxian
- Talaxian/Mylean (Neelix's great-grandfather was Mylean) (VOY: "Scientific Method")
- Talaxian/Ocampa (although they decided not to, Kes and Neelix seemed to imply it was possible for them to have a baby) (VOY: "Elogium")
