excerpt...
-
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.'
