I'm planning this litter, and having done the punnet squares, the litter would be - 50% aat, bb, CC, DD, Pp, sa* and 50% aa, bb, CC, DD, Pp, sa* (assuming the sire and dam are what they should and don't have any other genes floating around of course :lol: ).
My question is, what is an aat, bb, CC, DD, PP mouse? Is it a different colour because it's aat or will it just be a black mouse? Or even a cinnamon agouti? I'm assuming that because satin is recessive it won't affect the coat, and the same with p? Which means the other 50% of the litter would be chocolates?

I'm fairly sure I understand the codes, but not how the different locus add up to produce "xyz" colour. And I haven't the foggiest on how some alleles over-ride/hide others Any help would be much appreciated

It's chocolate tan. The at/a makes it tan and the b/b makes it chocolate.

BTW, Punett squares are only useful to a point on mice. For example, it might say you'll get mice who are at/at B/b and mice who are at/a B/B, but both mice might look identical. Every genetic combination does not have its own standardized name. In fact, most don't, because most genetic combinations look very similar to others.

I understand that, and in the case of B and b, the dominant B trumps recessive b so you wouldn't find out till you breed that mouse with a bb mouse (or another Bb). But I don't know how all the loci and alleles affect each other, so I thought I should ask to check.
Though after re-read my first post I have no idea why I thought there was a chance of cinnamon agoutis :lol:

 

[Jack Garcia]

I think you mean simply "cinnamon." That's an agouti mouse who is also chocolate (A/* b/b).

"Cinnamon agouti" isn't incorrect per se, it's just redundant, sort of like saying "PEW white" would be.

Ah okay I think the website I was reading up on genetics on was a little out of date with the names lol

Different names are used in different areas for the mouse fancy. It's not a matter of being out of date, it's a matter, like Jack said, of being redundant. Some say fries and some say chips, it's that sort of thing. Chocolate agouti(cinnamon) is a most memorable example of that, as they actually mean the same thing.

In Australia they have some different genes we don't see in the US or England; now there's a recipe for confusion! And the US and Europe have lilac and dove reversed, so I always say lilac(dove) or dove(lilac), trying to be clear, but often just causing more confusion. It all works out though, most of the time.
