Parti Doodle genetics

[Jennifer Tramell]

I don't have a parti doodle but I think they are just beautiful!  Someday, maybe :-)  I have a question that I ponder every time I admire your gorgeous guys.  Are there any f1 parti's? I have a chocolate f2 goldendoodle and I know from discussions in the chocolate group that chocolate f1's are rare because the golden retriever doesn't usually carry the chocolate gene.  Is there a parti gene? If so, does both parents need to carry the parti gene and can a lab or golden carry the parti gene?

Both parents need to carry the parti gene. So it is VERY rare to have an F1 parti of either LD or GD. I will look up the answer in the breeder forum though as I know it was talked about in the last year.

hi Jennifer,
the Parti gene is recessive in Poodles, and usually vacant from Labs. ONCE IN A WHILE a rare Lab will have a genetic pattern, such as the phantom pattern, or the piebald (parti) gene might be dormant in a Lab. But generally, that is why there are very few F1's with more than a white patch or a few white toes. I have seen some, but it's extremely rare.

The chocolate gene is recessive to black, in the same way that the parti or piebald gene is recessive to solid coloring, so you are correct about both parents needing a "copy" of that, or any recessive gene to get it to show up in the puppies.

Great question!

I know that the Tuxedo parti most commonly comes from the Retrievers - both Goldens and Labs have the St. John's Waterhound (now extinct as a breed) as a central forefather, and even Labs that have been purebred black for many generations can suddenly produce a Tuxedo. Goldens also have forefathers from two other distinct breeds that often were parti - the sand colored blood hound (usually has a black saddle) and the Tweed Water Spaniel (which certainly looks to me to have chocolate color).

St. John's Waterhound (the last two of the breed at an old age - looked exceedingly like Tuxedo Labs when younger):
