I guess I'm rusty on my genetics of GSP color. I thought you had to have b&w in both parents genes to get b & w litter of puppies. If one parent was b & w then other had to have recessive or be carrier of b & w genes in its background. Is this right or do you just haft to have b & w on one side to get a whole litter of b & w's.

A liver dog can not carry B or it would not be liver.
Two liver parents can not have a b/w pup.
A b/w can carry liver genes (b).
You need only one black parent to produce black.
You can have a whole litter of b/w with one parent being B - but I don't know how likely that would be and some of the B pups would carry b.
If I'm incorrect - please, someone, correct me. |

Yes you have to have one parent that is black to have black pups. Most people only breed black to liver. Some people do breed black to black but the hard part about that is that you don't know what pups would be homozygous black meaning two copies of the black gene.
Livers carry NO black gene
It is possible to have a fully black litter with one parent being liver and one being black but I don't think it happens very often. In my litter I had 5 blacks 7 livers. :0) |

| my litter last year was a solid liver to a solid black and I got 5 solid black 2 solid liver and one liver and white. Like the two above, you have to have a black varriation parent to get a black puppy just like you can only get solid pups from having at least one solid parent. |

| Pixie is correct, with the addition that if the Black Parent were Homozygous as Beth alluded to, the entire litter would present Black. |

Lets see if I have it right.
If you have a Homozygous Black bred to a liver, with absolutely no black in its background for 6 gen. you can still have a litter of all b & w pups? |

Homozygous black = BB, heterozygous black = Bb Liver = bb
Liver is recessive to black, so a homozygous black can only produce black, because any B passed on will result in black and B is the only thing homozygous black brings to the party.
Heterozygous black can produce black or liver.
Also two livers can only produce liver.
I hope this helps. |

We have bred our Solid Black female 3x and in all 3 litters she has produced either solid black or solid liver puppies. No ticking. A small white patch/ or ticked patch on her chest at best or a white/ticked foot. Two out of the three breedings were to a white/liver ticked sire. The third litter was to a solid liver sire. Predominant liver over black though. the first two litters she had 6 pups 3 black 3 liver. The second Three black and 6 liver. Third litter two black and 5 liver. |

2 livers can also produce ticked. |

Keep in mind that you must separate the discussion on color versus pattern. Here is a link to a discussion on Black vs Liver and Solid vs Ticked -- so differentiation of the color gene (BB, Bb, bB, and bb) vs the ticking gene (SS, Ss, sS, and ss) hopefully this helps:

The black bitch that was bred to a liver tick is likely homozygous for a pattern and not color... or solid as it were. I'm no expert in GSP breeding, but know a fair amount about genetics from horses, and color and pattern are two very different beasts. |

| True, true Dave and Cheryl. Cheryl, I believe you are also absolutely correct in your assertion as well, concerning pattern and not color. |
