I don't get it...

Non extension is written "ee" that would be recessive in my book. Steel is written "Es" denoting an incomplete dominant/recessive. All Torts and all Reds will only show those colours/patterns with two copies of the non extension; "ee"

And Japanese harlequin is "ej"

And when a rabbit gets steel and harliquin " Es ej" - it looks black!

Or if a rabbit gets two steel it "may" look black but may also look steel.

I'm just saying the E-locus doesn't follow the regular rules.

I'll never absorb this stuff, my brain is refusing and confused with it all, lol.
Is there one of those simple visual books that show real color rabbit pics with the code and then showing what and how this and that happens?
I keep looking over sites that explain it and all, but it's just going over my head... :/<br /><br />__________ Tue May 07, 2013 6:57 pm __________<br /><br />

Hm, I only get the light chin color when the AmChin is bred to a Californian. What makes it show only in that cross and not with the SF?

the chin gene is recessive to the full color gene. SF have the full color gene,C, though I know a few people are getting REW in their SF, c. Chin, chld, would need two chin genes, or a REW gene, c, or a himi gene-Cal-ch, in order to be a visible chin.

So the chin gene is dominant over the the himi Cal gene, but not over the full color gene in SF.

I am putting known genes on my pedigrees, and the ped I got with my new Angora also has known genotype on it as well.

I'm avoiding those lines with the 'white fox'.

Are all SF C or does that depend on their color? I can't find what a fox would be on the online color calculators. So I'm always bothering you guys instead...

The Nock rabbitry site has pictures with most colours - http://www.nockrabbits.com/coat_colors1.html

A silver fox should genetically be black with the silver gene expressed and not have any hidden recessives
= aa BB CC DD EE sisi

I know of some blue silver fox so dilute may be hiding in some black rabbit bloodlines
= aa BB CC Dd EE sisi

And if people are breeding to REW ( bad idea as you'll loose the long coat) you may get this hidden gene in your blacks.
= aa BB Cc DD EE sisi

If you inbreed or linebreed, these recessives are more likely to crop up since statistically 50% of the litter will also be carriers of these hidden recessives.

Lilac is more dilute of blue, er black, right? What is chocolate?

 

[Dood]

Chocolate is the B-locus. A chocolate Silver fox would be "aa bb CC DD EE sisi"

Lilac is a chocolate and dilute/blue rabbit so a lilac Silver fox would be "aa bb CC dd EE sisi"

it's not so much that they are breeding to REW, but chocolate is NOT an original color, you have to get it from somewhere, and when they bred in satins mostly to get chocolate, you are going to bring in recessives like REW. I don't have chocolates, and I won't have any. Many will recommend that you keep them out of your regular lines, as they are not part of the "heritage" breeding. Blue is part of the original breed, and I do have blues in my pedigree, though I have yet to have seen any pop out of this line.

Any outcrossing will likely diminish the coat of the fur breeds. I have noticed that very few AmChins have the 1 and 1/2 inch coat desired in the SOP, likely due to out crossing to improve body type, meat qualities or fur density, which would explain why my one AmChin carries REW, self and non-extension.

Amen to that!!! I'd rather just have blacks and blues than add chocolate and other colors and the coat suffers. That is why I am adamant about breeding Rex to Rex. It's hard enough to get good fur in the breed, much less bringing something from outside of the breed.

Re-thanking everyone who posted!
Thanks!

An agouti that carried non extension would look like any other agouti as its recessive

I disagree. The other 3 E-locus mutations (Es, E, ej )are co-dominiant or incompletly dominant and in my experience this is sometimes true with non-extension (e) and helps explain some of the vast variations in shades found in Agouti based rabbits.

I noticed that chestnut can "bleed through" harlequin and non-extension.

This chestnut doe carries non-extension, her sire was a tort.
I believe she shows the non-extension shading.
Interesting thing is, her opal littermates don't..

The first "black" kit is a self-steel. The light undercoat and presence of a wideband steel in the litter suggests that.

The second is a wideband chestnut. They are often called "sandies" or "sandy chestnuts". Genetically they are A_B_C_D_E_, just like a normal dark chestnut, but they are homozygous for wideband (ww).

The third kit is a chestnut: A_B_C_D_E_. Based on the litter, is probably a wideband carrier, but is NOT homozygous for wideband. So she's (Ww).

The fourth kit is a wideband steel. It looks somewhere in between chestnut and steel in appearance because of the wideband influence. Genetically this one is: A_B_C_D_Es_ww. You can tell this is a steel and not a chestnut because of the dark ear linings. There is only one gene that can cause that, and it's the steel gene.

So one of the parents of this litter IS a steel genetically, whether it appears to be or not.
