About Poodle Genetics Lab
Science-backed genetics education for the poodle breeding community.

Xyon Marley
Canine Genetics Educator and Author
Poodle Genetics Lab is the work of Xyon Marley, a canine genetics educator and author. Frustrated by how the science of coat colour inheritance sat locked inside dense academic papers and scattered forum threads, he built this resource to put rigorous, research-backed genetics into the hands of every breeder and owner.
His scientific foundation was built at the Faculty of Pure and Applied Sciences at the University of the West Indies, studying Animal Biology, Biochemistry, and General Chemistry, and expanded through medical studies at the People’s Friendship University of Russia, with grounding in Anatomy, Physiology, and Molecular Biology. That background is the framework applied to reading, interpreting, and citing the peer-reviewed genetics literature this work is built on.
The Poodle Color Genetics series is the result: a multi-volume scientific reference translating peer-reviewed canine genetics into decisions breeders can actually make. He publishes this work under the Poodle Genetics Lab imprint, an independent, breeder-neutral resource whose only allegiance is to the evidence.
Democratizing Genetics Knowledge
The scientific understanding of canine coat color genetics has advanced dramatically over the past two decades. Genes previously described only as dominant or recessive are now understood at the molecular level in most cases: we know the specific mutations in genes like MC1R, TYRP1, ASIP, PMEL, and MLPH that produce most of the poodle palette, from black and brown to dilution and merle. A handful of traits, including progressive greying and the exact shade of red, remain only partly understood: the direction of inheritance is known, but the responsible gene or the full set of modifiers is not.
Yet this knowledge remains largely inaccessible to the breeders who need it most. Academic papers are paywalled and dense. Forum discussions mix accurate science with misconceptions. Breeder-to-breeder knowledge transfer perpetuates decades-old errors. Poodle Genetics Lab exists to fix this.
How We’re Different
Peer-Reviewed Citations
Every genetic claim on this site is rated by strength of evidence and traced to its source, whether that is peer-reviewed literature or, where the science is not yet settled, clearly labeled as a working hypothesis drawn from breeding observation rather than a proven mechanism. We cite our sources and link to the original papers wherever a citation exists, and we say plainly when one does not.
Interactive Tools, Not Just Theory
The color calculator uses real genotypic probability calculation, not lookup tables. Enter actual genotypes, get actual Mendelian probability distributions, with health risk analysis built in.
Breeder-Tested Information
Every principle here is grounded in real-world phenotypic verification, not just theory. The science is checked against what actually appears in the coat, not only what the papers predict.
Honest About What We Don't Know
Canine genetics research is ongoing. Where the science is unsettled or where phenotypic prediction remains uncertain, we say so clearly rather than overstating certainty.
