A pink eyed cream as in a chinchillated fawn and very pretty I think.I always keep one chin buck just for surprises like this.He's just under 4 weeks old,going to be a big boy.It has always been my desire to have a lemon coloured mouse,hence the experiments.So far no actual yellow mice though.

Brindle does exist in the uk, I shared some of the first ones with Frank Ansell of Cornwall, very interesting to breed, I seem to remember the English ones have a problem with sex linkage, in that only the females are Brindles, I may be corrected on that !! it was 30 years ago !

Willow dragon ,yes they are in the shed and I have never experienced any health problems related to cold.They are the same as the others,provide them with the materials and they weave a warm cosy nest.

Shiprat,they are real brindles,I'm not sure why you thought that they are not available in the U.K

i'll be back,bucks and does are born but unlike brindles in the USA,bucks are not viable.They perish at about 10 days old.I have however and with much anticipation of great things to come grown a brindle buck to adult hood.Alas infertile.The does are perfectly strong healthy mice.

shown here with a correctly coloured sibling

They are a totally different type of brindle Matt :)

American Brindle is Avy, X-Linked Brindle (Which is what Sarah has) is MoBr.

The males die because of a severe deficiency of copper, because this gene prevents them from synthesising it. There has been tests in labs, where they inject male babies at 16 days old with a copper infusion to prolong life, but, as Sarah says above, the males even at breeding age, don't seem to be fertile.

The MoBr gene is linked to the X cromosome, but because females have two X's... the non attached X compensates for the copper thing, and females are generally very healthy.

As much as it would be easier for this variety to have the occasional male live long enough to sire offspring, it would then create the potential problem of non-viable females too, if they were homozygous and inherited the MoBr gene on both of thier X's
