The phrase "a derived group" is correct and usable in written English.
It can be used in contexts such as mathematics, biology, or social sciences to refer to a group that has been formed or developed from another group.
Example: "In the study of genetics, a derived group can provide insights into evolutionary relationships among species."
Alternatives: "an offshoot group" or "a resultant group".
A derived group variable that created a unique vehicle-specific number was used to control for clustering of passengers in the same vehicle.
In the O2a* network, the Hlai clade is much larger than the mainland or Taiwan part, suggesting that Hlai is much older than the mainland Daic or Taiwan aborigines, not a derived group of mainland Daic.
Three tRNA groups were evident: type II tRNA isoacceptors which were basal in the trees and could be constrained by few additional steps (low S), type I tRNA isoacceptors that were more derived and had larger S, and a derived group of three type I tRNAs (tRNAAsn, tRNAMet, and tRNAArg) with the largest S values.
These were later considered to be a derived group of annelids [ 7].
In this scenario, chitons are not primitive molluscs but rather a derived group, potentially adapted to high-energy marine shores.
Another highly supported (PP = 1, BP = 99%) interesting result was the position of the Halobacteria as a derived group within the class Methanomicrobia (also known as "Methanogen Class II").
Varieties of indica rice are found throughout the tropical regions of Asia and are primarily grown under lowland conditions, whereas japonica varieties have differentiated into tropical japonica, distributed primarily in upland tropical regions, and temperate japonica, a recently derived group that is cultivated in temperate regions [27].
It also has implications for the hypothesis that Africa was isolated from the rest of Gondwana from an early date as early as the early Cretaceous and consequently had a fauna distinct from the rest of Gondwana for much of the Cretaceous, as it may be closely related to the sudamericids of South America, India, Madagascar, and Antarctica, a highly derived group.
The Acalyptratae is a large, derived group of flies that also contains the families Drosophilidae and Tephritidae.
I now give further evidence that, although not as compelling as the polarizations discussed above, nonetheless also indicates that Gracilicutes are a major derived group within Negibacteria.
Leeches (Hirudinea), together with earthworms (Oligochaeta) form the class Clitellata, a highly derived group of the diverse Phylum Annelida or "segmented worms" (Rousset et al. 2007).
