I just love the really nice tans i have seen on this site, so I was wondering if anyone could tell me how to improve tan?

TIA :)

The most surefire way is to secure a mouse who already has a deep red tan and breed from it.

You could also breed a tan to a deep red (Ay/*) and cross the babies together. The same phaeomelanins (red pigment modifiers) are present in red mice and in tans.

Both these methods will introduce darker tans within a generation or two.

Otherwise, you're looking at hundreds of generations of breeding tan x tan x tan x tan and keeping only the very darkest-bellied babies.

It's important not to have any hidden recessives in tans. All the darkest-bellied tans who win awards are true-breeding or nearly so.

Ooh1 Me too!

I had tried breeding my best fawn to my tan and found out that that was the way to get a better orange belly on the fawn. silly me! At least it accomplished something useful even if it was backwards. I bet part of it'll be having a^t/a^t; after that I would guess breeding the best tan to the best tan to improve the color. Sometimes these things take finesse, sometimes they take time. I would also guess that not having any C locus dilution would be important. I'd also hazard that some top colors would be easier than others to get the fiery color with. I always wondered if the pink eye dilution made it harder, but then I heard that that actually makes it easier; I'm confused on that. :?:

Maybe the next one in line to answer will have something solid to say on the subject.

PE dilution does not dilute red pigment very much. This is why a red (Ay/*) can be nearly the same shade as fawn (Ay/* p/p). And that's why on a good dove tan (for example), the top color (black) turns grey but the belly color (red) remains the same.

Any version of red or fawn should work somewhat. A heterozygous (B/b) chocolate carrier) would probably be a good cross for tanning as well.
