Oddly enough, muscovies are thier own offshoot of ducks - every other breed is mallard based. So any other cross, it's a bit like breeding a horse and a donkey - you get a mule that is sterile (F 100% & M 99%).
Fortunately scovies carry genes for every color under the sun. Chocolates, Buffs, Cream, Bronze , Septia etc. are all naturally occuring tho some are found in some areas of the world and not others. Chocolate is sex-linked, single in F and double in M.
There's a wealth of genetic/color info on this thread with links to sites.
