These are the "racial" traits that the Treoxx apply to all of their bioid member species whenever they make their own versions of lifeforms based on collected tissue samples
1. Biological immortality - Treoxx do not experience senescence with increased age. It is unknown why the Treoxx find this desirable, but the trait does confer significant practical advantages in off-setting the need for care of chronic age-related disorders.
2. Regeneration - Treoxx can slowly recover from most injuries that are not immediately fatal, including regrowing lost limbs and organs in the course of a few Terran months.
3. Sterility - Individual Treoxx cannot reproduce. While Treoxx species retain the same anatomical and physiological primary and secondary sexual characteristics as their non-Treoxx counterparts, the Treoxx harvest and store the gametes of their members during fetal development. Biological Treoxx are grown in technological facilities, ectogenically.
4. Optimization - Because
