In deciding which color muscovys I want I ran across a site about color genetics. It says breeding chocolate with blues and blacks create sex-linked offspring. It doesn't say if other genetic characteristics ( pied or ripple for example ) effect the breeding results. Here's the wording from the website: (http://www.muscovyduckcentral.com/genetics.html) Chocolate is the only sex-linked gene. chocolate X chocolate = 100% chocolate chocolate X black = black drakelets that carry chocolate and chocolate ducklets. chocolate X blue = black and blue males that carry chocolate, chocolate and lilac females. chocolate X self-blue = black males that carry chocolate and pastel and chocolate females that carry pastel. chocolate X lilac = 50% chocolate ducklings, 50% lilac ducklings. I'm looking to pick up a few babies this coming weekend and they have a lot of colors available so any help would be much appreciated. Thanks!
