The maternity test serves to check the direct descendance of queens. Control over queens is a challenging task. Mating flight, swarming, supersedure and other confusions can lead to unnoticed queen exchanges.
Control of the ancestry of drone colonies is one of the standard services of a breeding station. We check whether the queens of the drone colonies show the correct ancestry.
Breeder queens are tested with much effort but can easily be confounded. The consequences can be dramatic for a breeding line. With the maternity test, uncertainties can be cleared.
