Thats the genotype of my female venere BbDd.

I know that because her mother was recessive mahogany bbDd and her father had to be Bbdd because there was all 4 colours in the litter she was born from and that her and all her littermates would be the recessive of their colours because its only possible to make all 4 colours (which also happen to be recessive) from a mahogany X grey if they both recessive.

Though if i breed her to my male who is recessive grey i can get all 4 colours but 12.5% will be dominant grey and 12.5% dominant black. 12.5% recessive mahogany and 12.5% tawny with another 25% each of recessive blacks and greys

so if she had 8 pups the statistical approach would be that 1 is dominant black 2 recessive
1 is dominant grey and 2 recessive
1 mhaogany and 1 tawny

If you breed a grey to a tawny and get all grey pups they however will all carry the gene for colour.

tawny to recessive grey will produce 50% tawny and 50% recessive grey

And all her littermates were grey?

if so then its likely she has a 50% chance that she can produce blondes and greys if mated to a blonde male or 25% dominant grey 50% recessive grey and 25% tawny if mated to a recessive grey.

your previous post though you said that romeo may alsoi carry but the fact her litter was all grey probably means she is dominant grey. But I cannot be certain.

well this has turned out to be a nice list of black or grey MALES who carry the color gene.

Garry I think that a public list may not be the answer....But I am certain that many people will be adding info to their websites about dogs carrying colour. Now that so many are interested.

Hey Link , I just thought in light of the statements about some very nice blondes out there that owners of a black or blue male carrying color,would have been delighted to at least place the name of their dogs on a thread such as this to inform owners of blondes or bitches carrying color what was available.
