Grey Dilution Gene

[kaeloch]

Hi all
I have a "thing" for coat colours in dogs having done quite a bit of research with regards BC coat colour inheritance in the early days so am really interested in anything I can learn on the grey Terv gene.
From what I have read, it is a dilution on the red affecting only the "non-black" regions of hair. One of my questions is, does a double-up on the grey gene (ie breeding grey to grey) produce more pronounced dilution - ie lighter coloured greys?
In BCs it is not advisable to breed dilute blues (not talking about merles) together as it often results in lack of hair on the ears etc with the doulbe-up of the dilution. Because the black points are unaffected by the dilution in the Tervs, has anyone any experience of the effect of mating two greys together?
Sorry if this has been covered previously - I haven't found anything in the forum so far on this.
Thanks

Because of breed standard at least in Finland two greys are ith short memory of mine, I am not sure it is ever done. But there are litters with other parent carrying heavily gray gene and there has been a full litter of gray dogs.
I have seen very rarely really gray dog, pure, silverish grey, mostly tghey are something dirty cream colour, also in the litters heavily carrying grey. I don't believe that they get more or less gray when combined only grey to grey, or red+red makes less gray.

This male is Tulisilmän Ascar, born out of red female and this:

Dujoiedevie Amaroq. Amaroq's grandsire is about gray Berlioz de la Grande Lande:


I am not into gray tervs, they should be red, but real gray dog can be born out of red parents and two gray ones do have no red pups, and I don't believe they get more grey.
Our dilute black malinois didn't produce any dilution in any of her litters, not even in black puppies.

Thanks for that. Always keen to learn!
Greys are ok in our standard here in New Zealand (although red is preferred.
My question is out of a real interest in genetics and how dilution works :-)
