A Genealogical and Genetic Examination of White and Parti-Colour Pekingese
Year: 2026
Type: preprint
Abstract: This study examines claims that white and parti-colour Pekingese originated from relatively recent crossbreeding with other dog breeds. The investigation draws on historical documents, FCI and JKC breed standards, registered pedigree information, a survey of coat-colour records for 150 ancestors, and published research on canine coat-colour genetics. The evidence documents white and parti-colour phenotypes within historical Pekingese lineages and shows that the breed standards do not assign these permissible coat colours an intrinsically inferior status. Established canine genetic mechanisms also demonstrate that a white coat, by itself, is not evidence of interbreed crossing. The study further traces a research-pedigree connection from a contemporary Pekingese to historical foundation stock. However, some historical parentage links remain unverified against original registration documents, and the research graph contains unresolved pedigree inconsistencies. These limitations are disclosed rather than treated as resolved. This deposit preserves a dated, identifiable version of the research manuscript.
