The simple answer is 'No', you will not get bi-colors if you breed to a black and tan dog that does not carry the bi-color gene. If you want bi-colors, you would have to breed to a dog that carries the gene, or another bi-color or a black dog. Breeding to another bi-color (depending if the second gene is black or bi-color) could give you an all bi-color litter. If your bitch carries a black gene as her second color, and you breed to a black, you could get bi's and blacks. If she does not, you would get all bis when breeding to a black. The black and tan gene is dominant to the bi-color gene which is dominant to the black gene. <G> And that was probably MUCH more than you wanted to know.
