DNA sequences that are close together on a chromosome tend to be inherited together. Because of this, we can use genetic variation surrounding a specific variant (i.e. "linked" to it) to infer the presence or absence of a variant that is linked to a health condition or trait. Linkage tests are not as predictive of your dog's true genotype as direct assays, that we use on most other genetic conditions we test for.
