The following is the only genetic mapping for scobies I've been able to locate. It's great as far as it goes (color) but it's not complete with mapping for patterning - what is dominant, recessive, incomplete dominant or sex linked. In particular I'm trying to puzzle out the genetics to produce calico scobies - white background with patches/splashes of both colors from the black and chocolate color palates. Breed sources do list this as a color and I've been assured from these sources directly that they have been observed occurring in FL. Other reputable scobie sources say they have never heard of such a thing. ********************** ME:Muscovy Ducks according to your website: Many other quite exotic colors have occurred - mostly in domesticated breeds, such as blue, blue and white, chocolate, chocolate and white, lavender and calico. S: suppose it depends on how you define “calico” … The technical definition is mottled colored, with a white base color with patches of other colors, such as black, brown, reddish / rusty or yellow/orange. Living in Florida, where Muscovies are quite common, I have seen quite a few muscovies that fit into that category … Sibylle http://www.avianweb.com – All About Birds ******************* while Barry Koffler responds: [email protected] Barry Koffler mid-Hudson Valley, New Yorkthe FeatherSite at http://www.feathersite.com Well, I've never seen a Calico Muscovy, for whatever that means **************************** So, calling all breeders for your observations, pictures and knowledge in an effort to produce a more comprehensive map of what's what! SHARE what you know or have observed! I'll table findings. THanks! credited source of genetic table http://www.muscovyduckcentral.com/genetics.html Aside from white, Muscovy come in two base colors, chocolate & black. All other varieties are derived from these colors. Black Chocolate Blue Lilac (Blue-Fawn) Silver Buff Self-Blue Cream Dark Ripple Chocolate Ripple Aside from the varieties noted above, Muscovy also come in 'patterns'. Patterns include laced, self, ripple, & barred. The self pattern is a feather that is solid in color w/out lacing present. Lacing is where the feather's outer edge possesses a darker tint than the rest of the feather. Barring is a pattern found most notably in juvenile birds. As barred birds undergo their first molt, the majority of the barred feathers are replaced by solid feathers with slightly barred feathers remaining only along the belly, flank, & back of the bird. Rippled birds remain rippled throughout life. The final gene worth noting is the white head gene. Birds that possess the white head gene can be any color as well as pied. Young or juvenile white head birds will appear to be solid birds with a few white feathers located on the head/neck. With each subsequent molt, the white will increase until the bird's entire head is mainly white.
