I have a question. Can you name some common combinations that could be mated to create Silver/Spot and Abacot/Snowy.
For example, if you had a fabulous Gray drake that you wanted to start with, what could you mate him over to eventually get to either of those colors? What would the ducks need to carry? How would the following generations go?
You can't get snowy without the harlequin gene, so to get snowy from a gray, you need to either already have a snowy to cross to it, or another color that has the harlequin gene like Spot, or a duck you know to be carrying harlequin.
Same with Spot, only in that case you also need one li Light Phase gene too, and the same applies to it as to harlequin. It needs to already be there or you need to have a duck you know carries it.
In my call duck breed book it refers to silver in England as being "our" snowy.
And spot or spotted as a different color. . resembling snowy.
Yes, I'd always read in books and online that Silver in the UK was our Snowy. That is why I said that in the original thread that spawned this one. But if the genotype of Abacot is this:
M+M+ li^h li^h e+e+ bl+bl+ C+C+ B+B+ r+r+ D+D+ Bu+Bu+
As @Upper Brook House Farm says, then that is indeed the same as our snowy.
Speaking of which, @Upper Brook House Farm I was going to ask in the other thread but didn't want to derail it further. What is the genotype of your Silver ducks?
