Genetics Help please?

Oh and I have another question I hope you all can answer.

What exactly is the color "squirrel"? I know what it looks like and I know it is related to chinchilla but I don't know how.

 

[Shaded Night Rabbitry]

Squirrel is a dilute chinchilla.
Like blue is a dilute black, opal is a dilute chestnut.

=D

 

[TCRabbitry]

Squirrel is blue chinchilla. Some breeds call it blue chin and others call it squirrel....

Also, I am confused still. I have done lots of research on rabbits in England as well, and have never heard of an Otter Martin....

Thanks.

Here's another question.

What is the difference between atA and ata in a tan pattern rabbit?

 

[TCRabbitry]

The difference between an agouti and a tan pattern?

I am not sure on the genetic code area, but from what I understand, it is a different variant of the agouti gene, so that only certain characteristics are expressed. An agouti has rings. A tan pattern animal does not. A tan pattern animal has some ticking, but no ring pattern that causes the distinct wavy pattern of the agouti colored animals....

That is exactly what I was thinking. So you're sayingthe big "A" is what causes the ring color, and the little "a" is just a solid tan pattern rabbit when paired with the "a[suP]t[/suP]" gene?

 

[TCRabbitry]

Something like that.

That would make sense, because an agouti can carry tan pattern, but tan pattern cannot carry agouti....

There are very well documented cases of two otters throwing a chestnut in NDs, from multiple very respected breeders. Personally I think it's one of those flukes in genetics, but who knows for sure.

That will be something very good to look into.

2 otters absolutely cannot produce agoutis - there's no such "fluke", just breeder error.This could easily be proved through a "paternity" test.

 

[TCRabbitry]

That's what I thought..... Being that Tan Pattern is recessive, and agouti is dominant, it would be impossible for a Tan Pattern to produce an agouti.

Just like it is impossible for two solids to produce a broken.

Yes - just remember that appearances can be deceiving. I've actually had a couple genetic "brokens" that were pure black except for white toenails (very minimal white). If I hadn't bred them and wasn't aware of the genotypes, I would have sworn they were solids.

 

[lelanatty]

How about this Pam:

Black otter X Broken black = Broken tort and black silver marten.

How do you explain that?

That one is easily explained:

Broken tort because one of the parents is broken and both parents are "Ee" in the E series,because each contributed an "e" to make tort.

Black silver marten because of the tan pattern coming from the otter and both parents carrying something recessive in the "C" series - At least one cchd (chin for silver marten) and the other parent carrying either cchd, cchl, ch or c in the c series.

 

[lelanatty]

Thanks! I was thinking about trying it again with completely different rabbits but I am not sure if it would work. However, I may because I don't want to get any more seal martens that have been passed off as black silver martens. The sable gene is my worst enemy at the moment.

Never heard of that... , I have seen brokens from two "solids", the doe ended up being a broken with no pattern expressed on her because when she was bred to a broken she produced a charlie.

False Charlie. They're annoying, and they're really douchey to get nice patterned animals out of, in my experience.

UNLESS you have proven said charlie, when bred to a solid, to produce 100% brokens.
