The phrase "a complex admixture" is correct and usable in written English.
It can be used to describe a mixture that consists of various components that are intricate or not straightforward.
Example: "The artist's latest work is a complex admixture of different styles and techniques, reflecting her diverse influences."
Alternatives: "a complicated blend" or "a multifaceted mixture".
Metakaolin forms a part of a complex admixture to self-compacting high-strength concrete.
First, our analysis confirms and extends Elena and Lenski's inference that the fitness landscape is complex, such that an overall measure of curvature obscures a complex admixture of interaction types, some with positive and others with negative effects on fitness.
Our results are potentially limited by the characteristics of the air pollutants in MCMA and the populations we are studying, namely ethnic groups with a complex admixture of ancestral populations as seen with Mexican mestizos.
The Arabian bufonid assemblage, despite being comparatively depauperate with respect to surrounding continents, exemplifies the faunal pattern of the Arabian Peninsula, namely being a complex admixture of African, Western Eurasian, and South Asian elements.
A number of breeds showed a complex admixture-like pattern, notably, Sopravissana, Merinizzata Italiana, Spanish Merino and Rasa Aragonesa.
To explore the potential for identifying more complex admixture scenarios, a simple classification rule was implemented.
Our study provides a theoretical framework for analyzing complex admixture processes that involve dynamic contributions of mutually isolated source populations to the ancestry of a hybrid population.
Future studies are needed to fully characterize the process of complex admixture and introgression between pigs of different ancestry.
We have shown that the wavelet variance contains additional information to identify these more complex admixture scenarios.
Third, we show that individual mutations contribute in different ways to the complex admixture of epistatic interactions.
For real multiple admixture situations, this classification framework could be extended to a more complex inferential setting (such as ABC), but this simple example demonstrates the potential for reconstructing complex admixture scenarios from the full wavelet variance profile.
