Show me your Melanistic Blanket GSD - Page 7

4Pack - forgive my ignorance - but on your dogs "deal" - I am not sure I am going to say this so I am clearly understood -

You had puppies out of these colors that came out Melanistic blankets

"I'm trying to work out how I got melanistic B&T, sable, and Bi-color in the same litter...

Here is how I see it. Father is sable, out of sable/bt and bt/bt
Mother is bi, out of sable/black and sable/bt "

VM-
You could get all 3 colors assuming the sire is a sable with bi or blk recessive.

No, the sire of my puppies is sable out of sable and black and tan..... 

Wow not sure what happened to that last post of mine but I'm NOT retyping that. Just look at the ped pics.

Yeah 4Pack, I know what the pictures are like, and I agree that Brix looks like a saddle back. HOWEVER, he is producing heavily melanistic bi-colors, not just in my previous litter (which included Bella) either. So my question is just...might it be more complicated than it looks? 

Mary, I did a square with Brix's parents; if his parents are sable and black/tan, then I think it comes out that the puppies have a 50/50 chance of a sable or black/tan phenotype. But since bi-color is recessive to both sable and black/tan, I don't see it anywhere on my chart, even if one of his grandparents were bi. JEEZE, what am I figuring wrong? Don't recessives eventually peter out? And here is the square for Brix's grandchildren, Bella's children:
             
              S              bt

bi          S/bi          BT/bi


bi          S/bi          BT/bi

This is Ignite across and Bella down. If Bella is bi, and her parents are BT and sable, she would in fact have to be BT because bi is recessive to BT... Is that correct? Then where did HER bi puppies come from? Where would the OTHER recessives be on the square, the possible bi, black, etc, from Brix's background? I hope someone can show me. I would have thought that a dog could only have one recessive, and it would be the other dominant gene from the preceeding generation.

If there are melanistic b/t dogs, might there be "faded" bi-colors too?

ACK! I knew I should have studied harder in college biology!!!!!!

Here's one of the pups when they were little, they had tar heels, penciled toes, tan vents, & were black behind the ears. They all grew up to look just the same, more like melanistic black & tans, but I had already registered them as bi-colors...oops! They're still very nice looking, & of course I'm not at all biased! jackie harris

That worried me too, Jackie. I was told just to register them as the color they were at birth.
