I was reading articles online when I read this" The REW can also carry the Tort/Sable Point color allele". @http://threelittleladiesrabbitry.com/geneticsprimer.php
I believe that the "tort/sable point color allele" refers to the non-extension
e, which produces tort and sable point, as well as orange and ermine. It's not directly related to sable - that is a result of an allele on the C series.
Self
a and sable
c(chl) + non-extension
e makes sable point;
Agouti A and sable
c(chl) + non-extension
e makes sable frosty aka sable ermine;
Agouti
A and chinchilla
c(chd) +
e makes frosty aka ermine;
Agouti
A and full color
C +
e makes orange.
Yes, REW can hide
e, but so can many other colors. Non-extension
e is the most recessive of the E series and therefore can hide behind any other E allele: Dominant black
E(D), Full Extension
E, chinchilla
c(chd), shaded/sable
c(chl), or harlequin
e(j). You'll usually only know it's there if you happen to get two copies
ee in the same rabbit (although it
can actually subtly affect some of the other E alleles if it's paired with them).
Which makes sense because everything can be hidden under REW. But how many generations back would have effect? I was looking for a sable on the pedigree. CC is the first of his colouring in all of the litters. He has kits that look like his sister.Recently Muffin's may had 2 more kits that were similar to his sister but lighter. Is this a case of their silver colour being a chinchilla colour? Or the fact that Chinchilla rabbits can be either “cchd-cchd,” “cchd-cchl,” “cchd-ch,” or “cchd-c.” ...and somewhere back down the line there was a crossing?
Or simply one of the side rellies that are not on the pedigree ? The father is black. Many thanks as always!
The sable gene is incompletely dominant, meaning shadings are influenced by what accompanies sable or what is carried.@ The Sable Gene
Chinchilla rabbits can be either “cchd-cchd,” “cchd-cchl,” “cchd-ch,” or “cchd-c.”
CC's mum Muffin Mays CC'S Sister Ghost pedigree with colours....
Because
e is nearly completely recessive, it can hide for many generations,
or it can completely drop out in a single generation. It doesn't matter how many relatives carry it; if one or both parents don't have a copy, a rabbit won't get it. And even if both parents carry one copy of it, the kit may not get it. Genetics is, in large part, the luck of the draw.
Only if at least one parent is homozygous for an allele - whether dominant or recessive - can you feel confident that any (and every) kit will get it.
I see on Muffin's pedigree that her color is listed as "silver," which isn't a variety in New Zealands, or any other U.S. breed, for that matter. In my opinion it's not super helpful in discerning what you're dealing with, and may actually do more to confuse things due to the fact that in rabbits, "silver" frequently refers to silvering from the
si allele, while "silver-tipped" refers to steel
E(S), which is
completely different.
But from the single photo, I'd say Muffin is an agouti, either a chinchilla <
A_B_c(chd)_D_E_> or a sable chinchilla <
A_B_c(chl)_D_E_> (possibly with the wideband gene making her so light for a chin, and her agouti markings so prominent). I would have leaned toward sable chin just because of the slightly off-colored (rather than crisp black and white) ticking, especially on the edges of her ears - in this one photo, on my screen, it looks more sable-y than black. But that can easily be an effect of the photo and/or my computer monitor, and since she produced ermines (the does), she would need to be chinchilla... unless the does are sable ermines aka sable frosties... or unless...
Unless CC's black sire was
actually a self chin...aaarrgghh!
We'll leave that aside for the moment, but keep in the back of your mind the possibility that some or all of your "black" kits could be self chins. Also, if the pedigree is correct (at this point I have my doubts) the black sire could instead be a self steel
aa E(S)_ .
So anyway, back to CC, which I now feel more inclined to call a sallander, i.e. a non-extension
ee self
aa chinchilla
c(chd). You said that you
bred him to a black (which carried the silver or is it steel?) kits were: 2 rew 1 chocolate,4 black (w silver gene)
which means he carries a REW
c behind his chinchilla
c(chd), and a chocolate
b behind his black
B, so we can hypothesize that he's <
aa Bb c(chd) c D_ ee>. The
D is there because he is dense color, not dilute, and although he could carry a dilute
d, we just don't know, so we put that dash after the
D.
I don't know what you mean by "black (w silver gene)" kits but we'll leave that aside for now, too.
Then you said you bred him
to (top pic) a broken black cinnamon tipped doe,Smokey Jo (out of Rew and a black carrying the silver gene) ....kits were: 4 silver tipped body and points, 1 chocolate, 2 rew.
The chocolate and REW kits confirm the genotype above, at least in regard to the
a, b and
c. However, I don't know what you mean by "broken black cinnamon tipped" doe or "silver tipped body and points."
I'm thinking this is the doe Smokey Jo:
But this is not a broken colored rabbit. Broken refers to a color "broken" up by areas of white. Some brokens (called charlies) have very little color, sometimes only around their ears, eyes and nose:
(image from
Rabbit Color Genetics: Pattern Gene EN for Brokens, Solids, & Charlies)
while some others (called booted) are almost completely colored except for some white on their feet, belly and chest:
(image from
Marked)
Smokey doesn't have any white that I can see. You said something about white on her feet (unless you meant a different rabbit since I see you said "him"):
The dark hair from Smokey. As a new zealand they considered him a solid/broken in the sense of white paws.
but if you're referring to paler foot pads, that's typical of sables and not considered white. Nothing in the New Zealand standard says anything about white paws - in NZs, broken colored is the same as broken in all other breeds.
Anyway, I initially suggested that Smokey Jo could be a silvered sable point (which genetically, is a non-extension
ee sable
c(chl)_ with the gene for silvering
si. That would be <
aaB_c(chl)_D_ee _si>.
But now that you've posted these photos of her fur
I'm now inclined to call her sable steel, <
Aa Bb c(chl)c D_ E(S)_>.
To be steel, she'd have to have an agouti
A, and to make self chocolate, she'd have to carry self
a. She's black based so
B, but again to make chocolate kits, she has to carry
b. She's sable
c(chl) but carries
c to make REW kits. She's dense color
D, but it's unknown whether she carries dilute
d so we leave that a dash. If she's a steel she's
E(S), but I can't guess whether she's carrying a non-extension
e since I'm not sure what you mean by silver tipped body and points.
Is this one of them? If so, you would call that ticking or frosting, not silver tipping - silver tipped is usually used to refer to what looks like white tips on dark hairs, not the other way around.
I can't be sure, but do I see pink eyes? If so, this is a himalayan
c(h), yet
another allele on the C series, which would not make sense
at all because we know the genotype of both CC and Smokey Jo. Neither is himi, and they both must carry REW, so there's no room for
c(h). If those are pink eyes, either I've got something terribly wrong (which certainly could happen!), or that kit isn't from CC x Smokey Jo.
Hopefully those eyes are actually brown, maybe with a ruby cast, because in that case it could be an ermine aka frosty (non-extension chinchilla), a sable frosty (non-extension sable chinchilla) or a sable point (non-extension self sable), any of which
would make sense. (I think CC's sib Ghost is an ermine or a sable frosty.) If that is the case, it would be very reasonable to call Smokey Jo sable steel (carrying self, chocolate, REW and non-extension
e) <
Aa Bb c(chl)c D_ E(S)e> , and CC sallander (carrying chocolate and REW) <
aa Bb c(chd) c D_ ee>.
From these parents, a sable point kit could get either
Aa or 2 copies of self
a, one or two copies of black
B, a dominant sable
c(chl) from the dam with a recessive REW
c from the sire, one or two copies of dense
D, and two copies of non-extension
e.
You still have that steel
E(S) in the mix, but you won't see that in self rabbits, and it is excluded - no room for it - in non-extension colors like ermine. It'll only show up in agoutis like Smokey Jo.
Oh my goodness, what a workout!!! Thanks! I'll be watching for more photos, since I have a feeling we're not done.
