Black goose, non black parents, possible goose infidelity

[TheGooseLord]

This is the dad (Boris)

This is the mom (Jimantha)

Only other goose we had when he was conceived (their first son, Noodles)

The child (His name is The Rock)

What the other 2 kids look like (literally exactly the same, no point in showing a picture of the other one)

Wth happened? What are the weird genetics behind this? Who is THE FATHER (dun dun dun)

The gosling in the incubator will have white wingtips. White isn’t so much a color as it is an overlapping shade over another color.
The white goose could be genetically grey, blue, or even buff underneath the white dilution gene, and she’ll pass on any mix of genes she has to her goslings.

I can’t say who the dad is but here’s a good guide to color and pattern genetics in geese https://www.backyardchickens.com/threads/our-guide-to-colour-and-pattern-genetics-in-geese.561779/

Also I have a Roman X Toulouse cross, the mom is white and the dad grey, but the baby had extremly dark down with white wingtips too, currently she’s grey with white wingtips but she’s a slightly darker shade of graphite compared to the rest of my grey geese.
