Explore SaarGen’s articles on genetic diversity, inbreeding, runs of homozygosity (ROH), and dog population management. These concepts shed light on the challenges facing purebred dogs and the Saarlooswolfdog.
A breed cannot be preserved through isolated, well-chosen matings alone. Preserving it requires coordinated management of its genetic diversity, active breeding dogs, effective population size, and future genetic options.
The Saarlooswolfdog does not simply lack good dogs. More importantly, its population has limited genetic flexibility. This article explains why multiple indicators, taken together, warrant examining a carefully managed outcross plan.
An outcross does not succeed simply because a cross has taken place. It succeeds only if the introduced genetic contribution is retained, distributed, and managed across subsequent generations.
A pedigree-based inbreeding coefficient is a probability estimate. DNA shows what was actually inherited. Sound decisions require genomic and population-level analysis alongside that coefficient.
Genetic diversity is not a technical detail. It is the biological capital that allows a breed to remain viable and fertile, retain options for selection, and evolve without reaching a genetic dead end.
Pedigrees estimate inbreeding. ROH show what is actually present in DNA. This evidence helps assess genetic risk and make better-informed mating decisions.
