On breeding for color

For those of you have interested in this subject, here's the skinny.

From hiiriforumi; I asked:

When one breeds in order to achieve a change in the color of fur, is there a genetic change that occurs along with the change of appearance of the mousie?

I think there must be some sort of change of genotype when there's a change of phenotype. Nothing else makes sense, considering what I know, however little that may be.

I've been reading about Cattanach's Translocation, absorbing it slowly since the material is highly technical. If nothing else, it will be educational. Thank you all for your help and encouragement. Knowledge is the ultimate gift that keeps on giving.

The mod answers:

So... If I understand correctly, you're asking whether the differences in colour / coat / etc. in mice have a background in genetics?

I have to make sure what you meant because what I think you're asking is kind of fundamental foundation in breeding mice and understanding how colours and many other things are inherited.

The answer is: Yes they do.

You should probably read Finnmouse's "colour varieties" -pages and then continue to Willys K. Silvers' The Coat Colors of Mice - A Model for Mammalian Gene Action and Interaction.

Huh... I really don't understand your question there... of course mouses genetics change with coat colour. A chocolate mouse has different genetics to a blue mouse!

Ohhh so this is like what I will be doing with my Lilacs, trying to breed for the right 'shade' of colour?

It will be like, all lilacs have the same basic genetic colour code, but there are lots of other stuff I don't know about working around that basic code to affect shade etc.

I guess its kinda the same thing with humans with blue eyes have different shades of blue! hehe

So these are the genes that lie dormant until triggered? Either in the womb during development or once born in the outside world?
