I would imagine breeding crosses ethically takes even more care & effort than pedigrees, not to mention expense if both breeds being used were to be tested

Many color genes and their inheritance patterns are similar across all dogs breeds (and in fact across many mammalian species). There are some very specific mutations that occur only in certain breeds however.

One of the very difficult things to work through, I find, for many that ask on this topic, is that there are MANY color genes that create a color and pattern in a dog, and you have to consider the interaction of all of them.

Another difficulty is actually knowing the color of the adult dog - as with many dogs the colors have changed since birth through modifiers. It is through the birth colour that you'll be able to figure out the genes the best.

An example of this would be Yorkshire Terrier pups. Yorkies are genetically a't'/a't (black and tan) on the agouti locus, just like Rottweillers in fact, but both breeds have different modifiers that contribut to making the colors look very different to eachothers in adulthood -a Yorkie's tan creeps into the black and modifiers lighten the coloring.

Anyway --- off for a walk, but before I do go here is one site that is quite good.

Dog Coat Colour Genetics

Feel free to post the colors/photos of the parent/grandparent dogs and I'll help you through what they might produce.

It probably could - but way beyond my knowledge levels particularly as it seems any colour bar chocolate is permissable - I will have to seek them out at a show as I am curious now - it must make for quite a colourful display - or do they tend to be reasonably standard colours?

I did try Googling it - but I could only find one website link with anything on it - and that was simply "under construction" - hopefully someone will be along soon who can advise you more - or why not start a thread on it?

ETA - do you find prospective owners have colour preferences, or because they are low in numbers, people are just happy for a puppy? It can be fun in Labs if you are expecting 2 or 3 colours with most people having a preference for colour and gender - could be fun if colours are 'open ended ' !!

Yes TT's some in all colours (we always have a colourful collection in the ring )- I have met a few chocolate TT's they are stunning! But they always lose the black pigment and often have very light eyes.
