gorgeous litter, ;D so lucky to get a DPP, before her, the only DPP's I've seen are Dove and Lilac (in the US), do you know if aa pp gerbils are more suseptible to the DPP trait then others? I can't believe you got so lucky,  any plans on potential mates for her? |

Well I think I've seen them on some of my black pieds but its just not noticeable unless they are really highly mottled. So I think its just more noticeable on aa pp gerbils.

That's so awesome!!! I wish I could get some DPP's!! *jealous*
;D

Hmmm...mates. I'm considering. I'll probably mate her with Fire on the Mountain, my deep Pied Argente Golden boy, initially, and meanwhile hope that I'll somehow get a male DP gerbil either off the same pair that produced her, or from elsewhere...or maybe her son. Or, that georgeous mottled Argente Golden male pup I kept from February's litter... hmmm...choices! Cheam's Fire on the Mountain (photo at 8 weeks old, he's an adult now):  |

Beautiful!
Is this somethign they will most likely keep thoughout there life?
I know my pied nutmeg has a dark spot, but i just thought it was part of a molt. ? ? ?

Apparently, yes! I'm not sure about a DP Nutmeg, how old is it? Can you post a picture? Is it spotted, because apparently this mosaicism only occurs on spotted gerbils.

My friend's gerbil had a litter of pups that all had dark patches...looked exactly like yours! They all drowned when their basement flooded, while they were away for the weekend, though  They were in a wire cage on the floor, (hamster cage) and the water went over the tray edge, and drowned the six spotted pups. |

Crazycritter, you know, your Snowy is the son of black Thurston, and a brother to Victoria. that means he is 1/2 brother of the DP pup and uncle as well. Since we now know he is spotted, there is a good chance he carries whatever predisposes gerbils to DPP. It might be worthwhile for you to breed a spotted burmese daughter to him to find out. Only if you want to...  |

Potential mates to the DP Sp. Sapphire pup: Fire on the Mountain, a deeply coloured collared and pied Argente Golden:  But I think he doesn't have the colour broken up very well on his back. Now, how about his son, Fiero:  Or should I stick with aa recessives? Might the dominant A gene cancel the DP out? Gosh I wish I knew what I was doing here!  |

Or should I stick with aa recessives? Might the dominant A gene cancel the DP out? Gosh I wish I knew what I was doing here! No it won't cancel anything because your not dealing with a normal gene but genetic mosaicism. This is thought to arise from a possible mutation in the body cells or even a chromasomal accident (eg, embryo fusion, or the opposite to identical twins) very early on in life. This "accident" or body cell mutation can enable a normally recessive gene to then express itself. Because this effect involves body cells and not germ cells, the mosaicism fails to be inherited. Even if the mosaicism did involve the germ cells , it still wouldn't be inherited, but the genes that brought about the effects would be. This explains why i doesn't behave like a normal recessive gene, and can dissapear for a few generations and then return. Mosaicism is applied to non inherited cases of spotting. When the effect is brought about by genes we term it bi-colour. I've noticed two other things about this phenomena in gerbils. The first is the DP effect, although random in nature will appear far more frequently on solid colours (as opposed to grey and gold agouti-banded hair ) and also it is much more noticeable or common in aapp gerbils. The second thing is that the actual mark seems to be a repeatable pattern, ie if you get flank or rump spots coming out, then usually if any are produced in further generations, these will also have similar markings. Also the incidence of them appearing will increase if you do decide to use them in a breeding programme, although as i mentioned earlier it doesn't have the same laws as a gene but can appear randomly in litters, and often it may be two or 3 litters later before any others are produced. They are well worth having a go with, and i quite often have some real nice ones appearing, The one below was a favourite at shows and always did well  ![]() www.gerbilsuk.pwp.blueyonder.co.uk/dppburmese3.jpg [/img] Eddie |

Has it been found that dark patching occurs more in heavily mottled gerbils, or is it just as common in spotted/pieds? Or does anyone know? |

Thurston and Victoria have done it again. They surprised me with a dark patched sapphire pup this time! And such beautiful colourpoint and burmese pups:
They were in a wire cage on the floor, (hamster cage) and the water went over the tray edge, and drowned the six spotted pups.
