Pure Blood

Depending on whom you speak, the term "pure blood" is either a derogatory phrase or a status symbol, it refers however, to members of a species that have retained their native ancestory. With interspecies mingling a commonly accepted practice, it is difficult for many bloodlines to have ancestors from a single species, crossbreeding is regularly seen within civilizations with high numbers of test-tube children.

Zetan Pure Bloods
Long struggling to force the evolution of their species, the Zetans have mixed several different DNA structures into their next of kin, hoping to prolong their life spans. This however has been a mostly fruitless effort as Zetan DNA is extremely violent, there have been several physical mutations though, most of which reclassify an otherwise pure blood Zetan, into a Dran, or "star born" having non-Zetan blood in them. A more natural Dran is born of a Zetan pure blood, and an 0g evolved Zetan, called Dropa, most Dran children will be more reminicent of their pure blood parent, and even if no physical deviations are present, are still genetically different. Within Zetan culture, being a pure blood is a double edged sword, it is a high-class status symbol as pure bloods are a minority, however, as superior genetics out weigh social status, it is difficult to tell where either rank on the social pyramid. To the dismay of both pure blood Zetans and Dran, the Dropa pure bloods are undoubtedly at the top of the pyramid, as they are the smallest Zetan minority, and have the most superior genetics of the biocompatible species.

Sirian Pure Bloods
Being a pure blood Sirian is generally seen as a negative thing, the Sirian civilization prizes bio-diversity, and thanks to their malleable DNA, splice genes from muliple species into one test-tube child. The results of which have created a seperate set called Splicers, whom have been born with less than 50% Sirian DNA, which is a difficult task to achive and takes several generations to reach, while there are high populations of Splicers, they are still considered an rarity and are treated with respect. This left pure bloods at the wayside, not helping public opinion was the more common acceptance of the old Sirian religious system, which had faded into almost cult status several thousands of years ago when they encountered the neighboring Erulon. Strangely, pure bloods are also seen as a rarity, the ones that do not try to lord over their brethren with genetic purity are usually put into positions of public prominance, especially as ambassadors and local politics.
