if your Black/tan sire has a "Bi-color" second gene, your litter will NOT have any black puppies....if his second gene is "black" your litter can have, blacks, bi-colors, and black/tans......this is true only if your bitch's genotype is " Bi-color/black...this is hard to discuss on the damn computer!...lol...FB --- On Fri, 7/10/09, Amy Greenhut <genoaktortoise@xxxxxxxxxxx> wrote: From: Amy Greenhut <genoaktortoise@xxxxxxxxxxx> Subject: Re: [ SHOWGSD-L ] Breeding two BLACK GSDs To: edwinx@xxxxxxxxxxxxx Cc: "freelist" <showgsd-l@xxxxxxxxxxxxx> Date: Friday, July 10, 2009, 10:12 AM #yiv1281318238 p {margin:0;} I have a litter of pups due next week. The mother carries the black recessive. She is a dark bi-color. Mick who is the sire is a dark black and tan. It is possible that he has the black recessive because Nichole who is his half sister, same dam is solid black. But there are no blacks at all in Mick's sire's side. I am hoping for a solid black because I have puppy people who want black. I really do not think there will be any blacks but there is always that slim chance. And that is the lesson for the end of next week!

I received two more private e-mails from folks believing that a black sire and a black dam can produce a black and tan puppy...I invited both folks to call me on the phone to discuss the matter, so far neither have done so....so I will explain it here publicly...each parent contributes one of two genes to all of its offspring.....since the color black is recessive a black dog must have two black genes for coat color, receiving one from each parent....the only gene this black dog can pass to all of its offspring is a black gene...so if bred to another black dog, all genes passed from that dog are only black genes....I can explain this much better on the phone...Ed Hill ===========================================================================POST is Copyrighted 2008.
