Interaction of Lavender?

[Phillisy]

I have a white goose (Sebastopol) who was sold as a lavender gosling to her previous owner. She ended up feathering out white. Upon purchasing her I contacted the breeder and found out she had a pen of solid lavenders (should be 100% lav offspring?), and a pen with white and lavender mixed to improve type (I’m assuming the whites would have been geese, not the ganders). This breeder only breeds colours, so it my assumption that the whites she used would be colour carriers.

I now have my white goose (presumably lav X white), paired with a dilute grey or blue SB gander (hoping this years offspring help me confirm his colour). If I understand correctly, lavender cannot be carried, therefore my white goose would not carry lavender. However, is it possible she could genetically be lavender if she was lav X lav but white? Could she carry blue or grey if she has lav X white parents? Or, if her white parent was a colour carrier, could she be carrying colour from them?



In a face value theoretical breeding scenario, not taking into account complex colour backgrounds, what would...
Lavender X True White = ?
Lavender X White colour carrier (breeder has grey - splash & SB, blue, buff, and lavender, all separated) = ?

For fun, and out of curiosity, what would either of those outcomes be if crossed with...
Dilute Blue SB Gander X ? = ?
Dilute Grey SB Gander X ? = ?


One day I’m hoping I’ll be able to grasp this whole lavender genetics thing lol.

I don't know goose genetics, but maybe this calculator could help:

Edit to add: that whole page has calculators for many kinds of creatures, but I think I did a link that will take you right to the goose options. There are two--apparently the person making them isn't entirely sure of how some of the genetics work, either
