Hybrid



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

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.

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". 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. 

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.
