Hybrid

A hybrid or mixed species was the end result of mixing two or more different species in the biological process of reproduction. Klingons referred to hybrids derogatorily as a mongrel. () Spock was also derogatorily referred to as a half-breed on a number of occasions. (; )
== Biological aspects ==
Because of the common genetic ancestry of most of the species of the Milky Way Galaxy by way of the ancient humanoids, many species were able to interbreed with or without the help of genetic technology. () 
According to Doctor Phlox, Humans and Vulcans were quite similar. () In fact, Bethany, a Human/Skagaran hybrid, was one of the first known hybrids encountered by Humans from Earth, confirming that such interspecies breeding was possible. ()
== Societal aspects ==
In some cultures, children who are born as a result of interspecific relations were rejected by the society of both races. For example, Bajoran/Cardassian hybrids were often rejected by both Bajorans and Cardassians. () This was, however, the same treatment usually received by Cardassian orphans, as well. ()
During the mid-22nd century, before such things were commonplace, those behind Terra Prime, such as John Frederick Paxton, believed that Elizabeth, a test tube baby-hybrid of a Human and a Vulcan was "a cross-breed freak," asking, "How many generations before our genome is so diluted that the word "Human" is nothing more than a footnote in some medical text?" ()
== Personal aspects ==
As noted above, Spock, a Human/Vulcan hybrid, had many personal demons when it came to his being.
In 2266, he shared with Doctor Leonard McCoy that "being split in two halves is no theory with me, Doctor. I have a Human half, you see, as well as an alien half, submerged, constantly at war with each other. Personal experience, Doctor. I survive it because my intelligence wins over both, makes them live together." ()
