Is the broken gene carried?

[paper_crane2]

If a rabbit has the broken gene in its pedigree, but is not broken itself, is there a chance that it will make broken kits?

 

[MamaSheepdog]

Nope, sorry. It is dominant, so will always show if the rabbit has it.

 

[akane]

Nope aside from a few situations where the broken gene is obscurred by another coat pattern (you can't see white spots on a white rabbit) you will see it if they have it. So unless you are breeding something like a REW if your rabbit isn't showing broken you won't get broken kits.

 

[paper_crane2]

Thanks! That is what I thought I just wanted to make sure.

IF you breed the unbroken rabbit to a broken rabbit, you should get some solid and some broken.

But they're right... unless you have something like a REW hiding broken, or a broken red rabbit with the chinchilla gene which hides red (I had one! It was a black-eyed white rabbit.), it doesn't have the broken gene itself. You won't get broken kits from that bunny without breeding it to a broken bunny.

Yes, reminds me of those broken himis.

At least you can usually tell if a himi is a broken because its feet (and possibly its tail) will be white.

I saw one instance where brokens were produced from two "supposedly" solid parents. In that case, careful inspection of the parent rabbits revealed that one of the parents had a white toe and a small spot of white under the chin; not enough to be noticeable on casual inspection. Still, the rabbit had the broken gene -- it's just that "modifier" genes, which affect the amount of color vs. white on the animal had made the rabbit look like it was basically a solid. Anyway, you can imagine the surprise of the breeder when they saw broken babies in the nest box from two parents that they thought were solids!

 

[ladysown]

you do need to watch for small spots, mismarks etc.

Some solids don't show those small areas well... so if you breed to solids and get a broken... somewhere you have a hidden broken.

You can also get the same markings with a himi marten or an agouti himi, if you don't know the difference.

Question... Its early for me so I'm sorry if this is a stupid question. My broken doe and my REW buck produced a litter that included three brokens so does this mean my buck is technically broken, but because he's white we can't see it? If he we're broken, wouldn't we get all brokers? We did get some solid blacks, too. Oi.. I should know better than to try and understand genetics first thing in the morning.

Most likely he does Not carry... if You had other solid kits in the litter.

Broken is dominant so that means you only need parent to have it to get the effect. Your broken doe likely supplied the gene to the kits but it is possible your white buck is broken,

Statistically a broken to broken breeding produces 25% Charlie's (two broken genes creating a mosty white rabbit) 50% broken and 25% solid. If this is the ratio you got in the litter then he's broken too.

Broken to solid produces 50% broken and 50% solid, if this is what the litter looks like then he is likely solid.

 

[Desert Rose Rabbits]

Gotcha... makes more sense now that I'm awake. Okay, so out of 10 kits: 3 are broken, 2 are chestnuts, and 5 were black so he most likely he doesn't carry. The reason the broken showed up is because of the broken doe and those 3 kits got the broken gene. The others, didn't but could possibly be carriers or because the black/chestnut is there, those guys are just normal solids?

 

[Dood]

They cannot secretly carry a dominant trait - it always shows up in the coat (the exception is REW and Himilayan will hide colours under the white) so the solids will never produce broken unless bred to one.

The key word here is statistically.

I had two does kindle the same day. Both were broken to solid breedings. One litter had five solids and one broken, while the other had one solid and five brokens.

I did get an even 50/50 split, but it took two litters to achieve it. :roll:

 

[skysthelimit]

I bred a broken to a Castor and go no brokens, twice. At some point if I had continued, I would eventually get some, though we are still waiting, maybe 5 litters later, to get a broken chin from the broken chin doe.

But statistically speaking, those are the odds.

 

[Honorine]

White factoring/Broken is an incomplete dominant, not a complete dominant. Thats why you get both brokens and solids when you breed them. While solids cannot carry broken what they can carry is 'pattern'. There are a number of different broken patterns and a solid rabbit can carry for a particular pattern, such as full blanket or english spotted. Booted can also be carried, I had a booted doe who would only produce booted, and her get would only produce booted, even the solids.

 

[akane]

My booted doe produces offspring with a ton of white and lots of spots. We call them dalmation mini rex. We were going to try to breed for it because it was interesting but the project lost out to others.

 

[Desert Rose Rabbits]

Oi! I'm telling you, rabbits are crazy with the whole color/pattern/gene thing. I've noticed that every breed seems to label colors differently. Is there a general set of terms that people use to describe colors when you're running meat mutts?

 

[Dood]

The letters used for genotype are the same regardless of breed but the broken modifiers (actually most modifiers) are not well understood and have yet to be classified.
