tell me about ruby cast eyes

[Zinnia]

Some of my litter have ruby cast eyes. Just dilutes. But the ruby cast is not part on the color description of those rabbits. For example, my fawn and lynx-like kits have a definite ruby cast.

The (opal) does not. The non-dilutes do not.

Here's what I know.

Each parent has C. Both parents have a 50/50 chance of either c or cchd. Well... I guess there is a slim chance of cchl - maybe... I see it up the line in a GGparent.

Can I make any guesses based on these eyes?

Does anyone know of a good reference for ruby cast....or how the different c alleles affects this?

Thanks!

Chocolate (so lilacs/lynx as well), chinchilla, shaded and dilute will affect eye colour.

I would guess that the fawns are chocolate fawns = A_ bb C_ D_ ee (cannot be chin or shaded would be frosty looking)

I forgot to say that I'm talking about a recessive c affecting the eye color. Not a c that presents itself in the individual with the ruby cast eye. I read that a recessive, carried cchd could show up as a ruby cast, but I haven't heard any good hard details about it.

The rabbits are presenting C, I think.... Fawn and Lynx.... But the recessive cchd may show itself through the eye and subtly in color presentation(?). I wish I knew more about this. I read a snippet every now and then about it, but nothing thorough.

My chocolate based rabbit do all have ruby cast eyes, and I also have recessive c rabbits that do not have it, if that helps.

Thanks,

That does help. Since those two rabbits in my litter are chocolate based....

And now I think I get what Dood was saying, too.

And, so I know we're talking about the same thing....

In some light, their eyes flash a red light from the pupil and the iris - the whole eye just appears as though you're looking at it through strawberry jello for a moment.

My blue eyed Vienna marked kits who are full colour but carry shaded have wonky blue, green and/or amber eyes but my harlequins (fawns with harli gene) who carry shaded all have brown eyes.

Maybe it just depends on the bloodline and yet unknown modifiers

Since we are on this topic.
I think some of my black rabbits who may have been carrying chocolate recessively also had a ruby cast.

Is this possible?
I have only test bred one to confirm it though. And yes, he did have chocolate.
I don't have the space to sort out and test breed whole litters though, and I never will unless I find a way to make more money out of these guys. :wink:

The information I've spotted occasionally is that it seems that a hidden cchd (and maybe also a cchl...I can't recall) could still make a visible impression in some phenotypes. I had not heard of hidden chocolate doing this, but I'm still new at researching rabbit genetics, so... The hidden cchd could appear as ruby cast eyes, and I remember there being something else in the coat that may be detected. But, I can't find either of those references now!

There may have also been a bit about this in About Bunny Colors. I need to look back through it to see. The thing is, I've just never found a lot of detail on it anywhere, but I think it would very valuable information for detecting hidden recessives. I'm with you...not enough space, money, good homes... to breed extra to verify it.

If I figure out where I saw this information, I'll post a link here. Meanwhile, if anyone out there has experience with this, chime in.

Yes. The SOP actually says that in chocolate based rabbits a ruby cast is permissible. In shaded rabbits a ruby cast is permissible. Chin does interesting things to the eyes. I find that in my chins and self chins the eyes range from blue, brown, gray and a mottled blue gray eye. If a black has a mottled blue gray eye, or blue eye, it's a self chin. If it looks not quite black, with a ruby cast, it's a seal.

My ah-ha after allowing this to steep in my brain for a while...

You're right (of course). Chocolate fawn could make more sense, as the only question I had with my lynx was whether he was lilac or blue (...sounds silly, but I've had little hands-on with color, so I'm just now getting myself tuned to each color). I REALLY felt that he was lilac with wide rings (sire had wide band...getting more bands as the weeks progress), but saw no other evidence of chocolate in the litter, so slight doubt lingered.

But with the chance of more than one kit being a chocolate base... Well that's more confirming. I hadn't considered the fawn to be anything but washed out black on the ear tips... I was comparing the lynx to the fawn's ear tip color...very similar, which (because I never thought of chocolate base for the fawn) fed the doubt.

But now, alas! It makes much more sense! Both ARE chocolate based and both have ruby cast eyes.

Thanks - twice.

So, chocolate based (lilac) fawn seems possible? He's smutty, and I read chocolate based creams and fawns were supposed to be cleaner... but his mom's got a fair amount of smuttiness, too...

Lynx is a chocolate based color. Depending on the breed, fawn is also a chocolate based color. Genetic lynx and sooty fawns are often only distinguished by the undercolor coat. Otherwise, on the show table, the sooty fawn and the lyxn are the same thing.
