In regard to breeding, pairing 2 partis will always produce partis, however the combinations of color and the landing areas of color cannot be predicted. One litter can contain a black and white parti and an apricot and white parti, with color falling in completely different areas.
It is the MITF gene which causes coloring
to appear in random areas in parti Poodles. Since the MITF gene is recessive to solid color (Solid color is a stronger gene), both dam and sire must be partis to create partis and a parti paired with a solid will most likely produce a solid.
Parti Poodles cannot currently be shown in AKC conformation events, and due to this some people mistakenly believe that they also cannot be AKC registered. This is not true. Partis are AKC registerable, with pre-designated color numbers, and can be shown in obedience and agility events. Many people feel that at some point in the future, they will be able to enter into conformation in the United States, as they are in other countries such as Germany.
It should be noted that partis were always very popular across the world. In the late 1900's, for unknown and unrecorded reasons, those in power decided to exclude them from the show ring. In 2002 the Multi-Color Poodle Club of American was formed and held their own conformation show in 2006, on the same day as the IKC's 12th annual premier show.
