Dilute or Tweed Dapple may also sometimes be called Patchwork Dapple or Additional unidentified Dapple modifier?

Having done quite a bit of research now this multiple colours in dapples may in fact be down to a dilute so currently I'm 50/50 on what it actually is. If you have information either way I'd love to hear from you. The one thing I am 100% certain about is that there are multiple colour dapples as you can see from the pictures below. It's what causes this to happen I'm not sure about!

(Tweed - Tw - can be shown as MmTwTw,MmTwtw Genotype)
Very very occasionally some dapples have additional colour patches to the standard 2 colour tones and this may be caused by the Tweed gene which is a dapple modifier. This gene when carried by non dapple dogs isn't visible so you have no way of knowing it's carried given it only becomes visible on a dapple dog. Obviously you can figure out who carries it if you are lucky enough to get a Tweed dapple in a litter - One parent Dapple with no tweed gene showing the other a non dapple colour must be the Tweed gene carrier! The Tweed gene makes the dapple pattern more than 2 colour tones, like the chocolate dapple dog below - NOTE the addition of a fawn colour tone giving in this case 3 colour tones over the standard dapple 2 colour tones. Or that could all be wrong and it could be some form of dilute!


And to make the differences easier to see I've digitally sampled the colours from the dog.

The gene can also work on a silver dapple producing an additional medium silver/grey set of patch's to the normal colour tones you would expect.

Normal dapples" are 2 toned (NO Tweed gene) or multi toned (with the Tweed gene/Dilute). Tweed gene is dominant to not Tweed dapple pattern and works only with the Merle gene (Dapples).
Tweed creates one or more extra shades of eumelanin, not counting the diluted (dappled) base and pheomelanistic points, if any. No currently known health issues with this gene other than those that already apply to dapple to dapple matings. Tweed is probably also know as Patchwork Dapple particularly in the U.S.A. where there seem to more of them than in the UK although in both countries they seem fairly rare. I must have looked at thousands of dapples over the years and the one above is the only one I have seen in the UK. If you know of more I would be really interested in hearing about them and seeing pictures of them if at all possible.

This may as I said earlier also be a from of dilute but on that front I have little evidence currently.

If you can add more information and or help amend/improve what I've written above I'd really appreciate it as there seems to be very little accurate information around. How ever what ever you choose to call them they do exist!
