A DNA test gives information about the DNA sequence of an individual dog at a position in the genome that is known to influence a particular inherited trait.
Most DNA tests are for a specific mutation that has been shown to cause an inherited disorder.
Sometimes the mutation causes a 'cosmetic' trait, such as coat colour.
Currently, most DNA tests are for mutations that cause 'Mendelian' or genetically simple inherited disorders.
Increasingly DNA tests will become available for 'genetic risk factors,' which increase an individual's risk of developing a disorder but are not the 'whole story.'
