Hi
It appears these Spotted Geese will likely be males and have others said the females will be a solid colour. From my understanding the genes responsible for the pattern are the sex linked Dilution gene and the Pied gene.
The evidience seemsto point that the Pied or saddleback gene is not sex linked but simply a recessive gene. However these Spotted males are also seen in Sebastopols andusually referred to as Splash Patterns. Genetically the Spotteds are Dilute males split for Pied.
I think there needs to be more work done on this as it appears the recessive Pied gene does have some influence on the pattern. A White Gander mated to Brown or Grey Goose appears to produce Splash (or Spotted) male offspring and Dilute females yet with my understanding of the present genetics all offspring are genetically identical, ie; Dilute split for Pied. Hopefully someone else will add to the discussion.
