Poodle Color GeneticsVolume I, Second Edition
The Science Behind Poodle Coat Colors
The most comprehensive single reference on Poodle coat colour inheritance, written for breeders who want to understand the science rather than memorise rules. Referenced against the current peer-reviewed literature, with reference plates and inheritance tables throughout.
- 348 pages, Standard Color interior
- Covers the E, K, A, B, D, G, S, M, I, and R loci
- Health risk guidance for merle and dilute combinations
- Amazon paperback or direct PDF eBook

What’s Inside: Chapter by Chapter
Ten comprehensive chapters take you from foundational genetics concepts to advanced multi-locus analysis and practical breeding applications.
An accessible introduction to Mendelian inheritance as applied to coat color, covering dominant and recessive alleles, homozygosity vs. heterozygosity, and how gene expression translates from DNA to phenotype. Written assuming no prior genetics knowledge.
Substantially Updated & Expanded
Owners of the 1st edition will find significant new material throughout. The 2nd edition adds substantial new content, not just a light revision.

Xyon Marley
Author & Educator
Written for Breeders, Backed by Research
Xyon Marley is a canine genetics educator and author. He writes and publishes under the Poodle Genetics Lab imprint, an independent, breeder-neutral resource focused on the genetics that actually shape a breeding program, grounded in the current peer-reviewed literature rather than folklore.
He built Poodle Genetics Lab because the science of coat colour inheritance sat locked inside dense academic papers in journals like Animal Genetics and PLOS Genetics, out of reach of the breeders and owners who need it most. The Poodle Color Genetics series is the result: a multi-volume scientific reference that translates that research into decisions breeders can make with confidence.
