If he's DD, than there is no problem and he's not a carrier ... it's a 40.00 test. |

It says the blue borns have 2 copies of the recessive dilute gene which means that both parents are Dd and the pup got a copy of the recessive "d" from each parent - making the pup dd.
There are tests available for the D/d gene. The company I've used in the past for coat color testing is Animal genetics ( Animal Genetics) and you would want to test for the D locus. Good luck. |
