Hey gerbfans! I have 7 pups. 3 of them are spotted Siamese, but I'm not sure if these 4 are also siamese or not, because they are so light and offwhite-ish. Parents are suppost to have the following genes: Mother: Siamese, aacbchD(d)E-G-P- (might have the diluted gene) Father: CP Nutmeg, aacbcbD(d)eeG-Pp (might have the diluted gene)   Thanks!=) |

I have no idea! But it would be quite strange to have only Siamese pups when you have the genes for more colours? One of them does look a bit darker than the others - but you are right - there aren't really many things they COULD be other than Siamese; I mean aa BEWs normally have darker ears - but I don't know how the Dilute gene works with Spotting - that could lighten them? I know Spotting can lighten the coat generally...
I think you can rule out any type of Burmese, and probably even normal Siamese, so this only leaves you with D Siamese from your safe genes. But they are a different colour - so there must be something else in there...
If you assume that there is another e - then you open up the BEWs - so CP and DCP Nutmeg; as well as LCP and DLCP Nutmeg - possibly explaining all these seemingly white babies.
If you assume the uwd too (outside chance); then you can get CP, DCP, LCP and DLCP Silver Nutmeg!
Have you any history on the Siamese to rule out any of the above genetically as it is easier than visually!

It is indeed very strange to have only siamese, but it's just a matter of chance. The previous litter contained both siamese and burmese. I don't have more genetic info about the Siamese mother. These pups are the same pups as the ones I suspected to have dark spots (http://gerbilforum.proboards.com/thread/30591/new-litter-dark-patched-gerbils) The pups have opened their eyes more and it seems they have red eyes. Which is strange because they are not really white, but cream-like. Here are some more pics by daylight:  Red eyes  Creamlike colour and darker spots.  Daylight shot, colour seems off-white.   Any thoughts?=) |

Well PEW would be the only obvious thing here as that is the only colourpoint colour that has pink eyes apart from Himalayan, but you didn't think you had a Light CP Nutmeg, which you would need to get a Himi. And pink eyes rules out all the nutmegs I mentioned earlier.
So, PEWs are usually as white as A4 paper, but yours have the blobs on them which is affecting their colour, so I would love to see some better images of them that show off the different colour. Does the dark patch go down through the entire hair, just on the surface or just on the skin? Does the fur seem different on the patches?
I had a colour changing PEW before, but only on moult. She was actually a Red Eyed Silver Nutmeg, underneath the PEW blanket, and that cream came through when the hairs died before falling out.
Interesting.

Also, are the dark patches in exactly the same place as they were when you first saw it, or are the patches moving around on their tiny bodies? If they are moving, then it is more likely to be straining our something to do with their moult, but if it is identical then that could be something else.

Most likely stained PEWs. In the thread before, it was the darker pups that looked patched; now it's the lighter ones. That suggests that there's something causing staining.
If you're certain both parents are L/CP, the only red-eyed pups they could have are PEW or DTW (and DTW only if they're both LCP).
