Pure Chamgagne had white babies!?

[Vankeerkp]

Still learning about this breed. We recently welcome a litter to a first timer. We were expecting black babie, which there were....there were also a couple whitish ones, kinda light grey

Does anyone know why?
Thanks

Here is a pic of them

Are mom and dad Champagne D'Agrents? I know Creme D'Agrents are their counterpart. I 'm thinking the more silver colored baby probably just isn't colored to standard.

 

[Vankeerkp]

Yes, both are pure. This was our first time line breeding this buck back to one of his offspring.

I don't know much about the breed, maybe it has something to do with your rabbits linage? Do they have any other breeds in their pedigree (if they have one)? All I can think of is that or maybe some times in this breed a silver instead of black kit is born. Whatever it is, it's genetic and if I had to guess the kit is healthy.
Another thing to help explain this is maybe you join the Champagne D'Argent club and talk to a few people there (I can't remember if the ARBA spreads to Canada).

Looks like it is a bleu
Some lines of argente rabbits do have blue in them (especially lines that have brun or st hubert in them), but its not common and not desirable in a purebred champagne

Hmm. I will have to look at pedigree. Really wishing I had a complete one for the grand-dame...nice lil fat bun tho

This is very interesting! I think I might know what's going on here.... Here's my guess:
Champagne D'argents have the genotype aa B_ C_ D_ E_ sisi
So for the "D" gene champagnes are "dense" (aka black).
They can either have "DD" with two dominant genes, or "Dd", with a recessive. Since the "D" dense gene is dominant, even if they have a recessive "d" gene they will still be "dense" aka black, and look the same as the others.
Your doe and buck have the genotype Dd. They are black (dense) but hold a recessive "d" dilute gene, which was passed onto this lighter colored offspring, which has the genotype "dd" dilute. This makes their coat color lighter and more of a blue. This would be not desirable for show rabbits, but I bet it will be a beautiful bunny!

This cross would have a 25% chance of producing a dilute "dd" kit.

I would love to see pictures of this kit as it grows and begins to silver. It's super interesting!

I will post updates! It was a litter of 5. 2 were this color the other 3 were black( as expected) saldy we lost 3 and are left with 1 of each, now called Yin and Yang( because why wouldnt they get called that!)

Here they are. 1 week old this past Wed.( with and without flash)

 

[Vankeerkp]

Update time! 3 weeks old now. Doing pretty good as well...still wondering on this one's color.

Looks like its actually a pointed white. It will get lighter as it gets older. That likely means that a Californian was bred to that line of champagnes (which some people might do to try and improve the type of the champagnes)
