Organisms have only two types of traits: primitive and derived. Primitive traits are those inherited from distant ancestors. Derived traits are those that just appeared (by mutation) in the most recent ancestor -- the one that gave rise to a newly formed branch.

Derived - Wikipedia, the free encyclopedia
In phylogenetics, a trait is derived if it is present in an organism, but was absent in the last common ancestor of the group being considered. This may also refer to structures that are not present...

Transitional fossil - Wikipedia, the free encyclopedia
Transitional fossils (popularly termed missing links ) are the fossilized remains of intermediary forms of life that illustrate an evolutionary transition. They can be identified by their retention...

As expected, based on the fact that HOMA-IR is derived from fasting insulin, both of these traits are phenotypically and genetically highly correlated. These two traits may reflect relatively more of the insulin-resistance phenotype.

It also clarified the relationship among the traits associated with cocoa butterfat and cocoa powder yields. Several promising varieties with multiple traits were identified as good candidates for parental stock for breeding programs.

Direct and maternal genetic and environmental variances and covariances were estimated for weaning weight and growth and maturing traits derived from the Brody growth curve. Data consisted of field records of weight measurements of 3,044 Angus cows and 29,943 weaning weight records of both sexes.
