Parentage verification is based on the comparison of genetic information from Offspring, Dam and Sire. From each sample/dog, a DNA-profile is established using genetic markers. There are a number of technologies available for creating this genetic/DNA profile, including the very common ISAG panel. The process of parentage verification involves a comparison of the genetic information present in an offspring with the DNA present in the possible parents. For a correct parentage, all genetic information in an Offspring must be present in the combination of Dam and Sire.
