Rat color question

Hey so we've got an interesting litter of babies here. I'm having a hard time telling what colors they actually are! I want to say that they're Ruby Eyed Dilute platinum, silver or mink but I can't really tell. Their eyes are definitely not pink like an albino and their coats are not like any of the other ratties I've got.

Any ideas there all you rat color experts?

I know this girl is a dumbo variberk, not sure what the name of the color is.

Here's a litter pic (what's left of it) ALL dumbos!

They're about 6 weeks old so I don't really know if they've gone through their first molt yet but I'm guessing not.
Also there's this little guy. I'm definitely keeping him :) His name is Ace and his colors kind of have me puzzled he seems to be half fawn, half agouti which I've never seen before anywhere. I think he's a pretty cool looking little guy :) Anybody else ever seen this before?

The father of this litter was my fawn hooded and the mother was a dumbo seal point siamese.

I would trust Connie for a final answer, but I think both may potentially be siamese as well, but only time will tell. I think Ace has a better shot of losing the color through the body and becoming a siamese.

I dunno...I am just happy I produced a self in my last litter.

I have to say, that is a somewhat unusual looking litter.

I have seen my fair share of Triamese, but none with back stripes quite that dark. Usually their stripe is a pretty light (almost) beige. Something also strikes me as odd with the appearance of a high white mark on some of their heads.

Also, unless it's your camera, the Siamese seem to be a bit darker than most.

In conclusion, if you twisted my arm, I'd say Triamese and Siamese. They just might be darker than most. This might just be one of those wait and see litters. :)

Yeah the blaze on their forhead has me kind of confused also, but I'm assuming that it's a "recessive blaze" or just a random thing since neither of their parents are high white and neither are blazed. I'm really psyched by the appearance of this litter so I'm going to be holding back Ace and the girl in the first picture. They may just turn out to be Siamese or Triamese (that would be cool lol) but they're both wicked sweethearts.

What were the parents? On my computer it looks like the contrast has been turned up too high, which gives them a darker appearance. But they definitely look like some form of marked siamese.

Oh just saw the parents colors at the bottom hiding there.

Well, they are all agouti if the father was truly a fawn (Aa, rr). Agouti is a dominant gene, RED is recessive.

Sounds like the mother had a genotype of aa, ch ch.

I've read that if you have the Agouti gene with the siamese gene, it will end up with a washed out Agouti color. However these ones certainly do show the traditional gradient associated with siamese, and given at least one animal is black, the father may have carried the recessive black gene.

BUT, if the father was not a Fawn (which I highly suspect), where he was in reality a Beige (aa, rr), the babies would be marked siamese (this assuming the mother does not carry any "rr".

But, I can't say for sure because the pictures are quite dark, but I will concur with Crissy, that they are siamese and marked siamese, or rather, triamese.

BTW, the head spot is not considered a blaze, blazes are quite different. That is a white spotting mark from the varigated..

Very cool, thanks Connie :)

Here's a couple pictures of the parents:


Stuart, the father. I'd assume that he's a Fawn. I know that he's had a lot of black babies in his litters so he does carry the black gene.

And here's Daisy, the mother.

I dont think daddy is a fawn...again, trust Connie on this, as I am pretty much pestering her constantly about rat genetics now(thank you Connie!), but I thought fawns were made with dilution from RED, and since dad doenst have the ruby eyes, I dont know if he can be a fawn.

If it helps any...
