She's done it again. After moulting back to pure white last time after only 2 weeks, she has since moulted again; and in 2 days she now looks like this: WOW! There's a little bit of the colour on her nose too. I have enhanced an image showing her rump closer and it is a little patchy in places, but you can see it better. You can also see paler blotches running up her back if you tilt your screen: So, do Mosaics usually keep flashing up their genetic effect in different places? Or is it actually connected to the process of moulting itself. Or is it something totally different? Obviously we shall wait and see how long the colour lasts this time and whether it increases in size first? And yes, she is currently pregnant so I am also considering hormones to have played a part in it this time.

I thought mosaics were only found in spotted gerbils as it's linked to the dominant spotting genes. Or with self ee gerbils, expressed as dark spotting. Is it possible that it's a chimera?

I don't know - that's why I was hoping someone could offer some suggestions. I know you can't pass on Mosaics genetically, but I was more interested in whether Mosaics or Chimeras were ever know to get rid of one patch and then re-grow another one somewhere else.
I mean has anyone out there ever had a colour-changing gerbil?
I will read up more on Chimeras anyway as I originally focussed more on Mosaics as when she had the first patch, that fitted the bill best.
Hmm?

From what I have been reading, chimeras are permanently affected by this condition - so if a person had 2 different colour eyes due to being a chimera - they will always have different colour eyes, etc. It is usually that way from birth until death.
And the ones only found on spotted gerbils were the dark patch (DP) gerbils.
However, I have read that Mosaics are more transient, but nowhere can I find info to say whether it keeps recurring and in different places? And I need to find out more about changes to the hair on moulting although it was once suggested that 'dead' hair being moulted out wouldn't change colour.
I will keep reading...
