One last question ... do you think these genetic codes match up with the colors listed ( just theory ) BROWN

BROWN E/E b/b D/D AND C/C

BEAVER E/E b/b D/d AND C/C

LIGHT BEAVER E/E b/b d/d AND C/C

LILAC E/E b/b d/d AND C/c

WHITE CHOCOLATE E/E b/b d/d AND c/c ( PINK POINTS LIGHT EYES )

     

  • one minute...

       

  • I only know of a single dilution for a solid ie: black to blue or brown to Beaver (as it’s now referred to in the AKC colour codes for Poms – some people call it beaver, lilac, lavender, isabella etc.)
    As for E, it shouldn’t matter if it's E/E or E/e - just the same as D/D or D/d will produce the same result. If it were e/e, well then it would completely disregard the Agouti gene and the dogs would be a variation of red/orange to cream. C, I just don't know. Maybe C only dilutes the coat and not the points? Who knows? Maybe it does nothing in dogs’ colour but does something we haven’t recognized yet...
    We use an ‘x’ to denote either option. So E/x would mean both E/E and E/e because both have the same result. This is how I would describe it:
    Brown - E/x K/x b/b D/x - as long as it isn’t e/e, E doesn’t matter.
    Diluted brown - E/x K/x b/b d/d - the CKC and AKC only allow for one dilution of brown.
    Black - E/x K/x B/x D/x
    Blue - E/x K/x B/x d/d
    We believe true ice white to be E/x B/x D/x - black points. If it was d/d I would expect the points to be blue. This is why I can't believe that D has anything to do with white coats. d/d most definitely dilutes the points.
    I guess I would think of white chocolate as E/x K/x b/b D/x - brown points. If it was d/d I would expect the points to be diluted brown ie: Beaver, lilac, lavender, Isabella – whatever you want to call it. I must be some other gene or gene(s) not yet identified that affects the coat but not the points.
    I think there are different intensity genes that can affect the tones of the blues and beavers so they can appear lighter and same with e/e reducing red to cream etc. but it can’t be d/d because the points would be affected as well as the coat colour
