The reason that w2hite boxers are born is because of the markings on one or both of their parents being white, giving rise to soem that have too much white. Using a white for breeding witll increase the risk of producing even more whites, with the increased risk of deafness, adn ist ia a color pattern not acceptable in the breed ring.
I know boxer breeders and they curse when theya re wanting to keep a pup, as often the sex they want or th4e nicest shaped head or whatever is on the white pup which is no good for showing.
At one time white boxer pups were put to sleep at birst, as there wa no way of really testing ro the hearing. It is still heart breaking to ahve them tested at 5 weeks plus only then to find they are deaf, so I suppose some breeders would find it easier to ahve had them put to sleep at birth.
So basically it wouldn't be a good idea to bred from your dog, as even if it passed it's health tests it's colouring would mean a higher risk of producing potentially deaf or hard of hearing pups.
