Duckies!
Interesting. At what point does it become inbreeding then?Yes, they are different genes. But, different alleles can be acquired from different crosses but they all started out as mistakes or mutations when the DNA was copied. People liked those mistakes and purposely bred siblings together to get more. After a long time, your whole flock has a particular set of traits and we say it is a new “kind” of domestic duck.
