Sebastopol genetics doubts

[Urte]

Hi all,
I have a question, a friend of mine has a very large flock os sebastopols, he had some backyard geese too, and some crossbred and now he has mostly pied sebastopols.

Im gonna take home 3 pairs, but i want to go back to pure white sebbies.

What can i do? Take the whitest i can get and then select every generation?
Some Ganders are pure white, but no females that i could identify.

I’ll look foreward for your comments.

@Pyxis probably has the best grasp of goose genetics.

Lets hope he/she finds some time to drop some lines here to enlighten us!

So white in geese is a combo of the Spotted gene, aka Pied, and the sex-linked Dilution gene, which is the gene that makes, for instance, Pilgrims hatch different colors for each gender.

So to get back to pure white, you need to combine those two genes.

Doesn't matter what color pied, white will 'cover up' the color.

So you know what a pied looks like, of course. For Dilute, the females are mostly gray. Males are mostly white. Look up Pilgrims and you'll know what the color looks like.

Pied is recessive, and Dilute is incompletely dominant, so you most likely won't get white right out of the gate on the first cross. But keep going and you'll get there.

Thanks!!!
I get it now.
And based on the pics I posted that are of the flock from where I’ll be getting my birds, you think I will get to pure white eventually? 3/4 years maybe?

And what type of selection must I do? Only keep the whitest every year? What would be your advice?

Thanks in advance

Hi. Are you selling any of your Sebastopol's eggs? Thanks

First I’ll try to get them back to white, and I’m from Argentina, a bit difficult to ship you some eggs!!
