Question # 1: In times past, the blue color was considered as rare in the breed. How are
kennels now producing blue dogs in such great numbers?
The D Locus pair is the loci that modifies the dark Pigment pattern to blue with the
homozygous recessive (dd) alleles. Because kennels are selecting blue individuals which are
homozygous recessive (dd) the only allele that a blue parent can give to their offspring is the
recessive (b) allele. Breeding two blues together doubles up the recessive trait to (dd) which
modifies the dominant (As) allele to blue. If a resulting offspring happens to get the (Ay
) allele
from one of its parents, then the (dd) will modify this color to a fawn/bluies. If breeders are
breeding dogs for the blue color, since the gene is homozygous recessive, 100% of their
offspring will be (dd) and depending on the (As) or (Ay) allele on the Locus A series will have
blue or fawn/bluies pups.



Question # 2: It is possible to produce a puppy with a black nose from two parents, both
with red noses?
The red nose in our breed is produced from the Locus B pair with the homozygous recessive
(bb) genotype in combination with the (Ay-) genotype. Mating two dogs with the genotype (bb)
the result would be 100% of the pups having red noses (bb). If a pup with a black nose was
produced in one of my litters where both parents had red noses, then DNA testing with
parentage verification would be necessary to determine the actual sire to the black nose pup.
New alleles can be produced through mutation, but proof of parentage would have to be
determined using DNA to rule out a duel sired litter.



Question # 3: Where does the chocolate color come from?
The chocolate color comes from the Locus B pair with the homozyous recessive (bb) in
combination with the (As) allele. The dilution gene (dd) will also modify this dark chocolate to
a light or almost milk chocolate. In most cases, the nose color is also light brown or as we say
‘chocolate/red nose’.




Once you read this and you get your dog DNA profiled you can figure out with a genetic diagram that you were taught how to do in 8th grade and see what 2 dogs or what ever else can possibly produce im not a dumb hillbilly i do my homework and dont breed dogs unless it is good for the blood line and yes Clyde and Bonnie both have recessive traits to get the chocolate and the red but if you see the DNA profile on them its the only pair they have so it isnt that bad and when i breed them if i breed those two if they produce 100% red nose pups i will not breed them again because the recessive gen is dom that is why bonnie is being breed to luke for a better DNA profile for a start on my yard to breed to clyde im not putting your dog down im letting you know how i feel and how the rest of the game world sees it and you can lay the f off me and the box thing i breed game breed dogs not game dogs never have i said that my dogs were game and i think ive said a few times i raise game breed dogs cause to me that is the APBT my dogs would never be asked to get in the box so get that out your head never clamed I had game dogs just game breed dogs so i hope this clears it up for ya it to make it clear even more as I posted before a blue dog from my yard will be Sterilized and sold or given away as pet quality only that is Culling to me wouldnt kill it cause it turned out the wrong color thats my program not yours cull all your red dogs if you want
