'Mutation' genetics

[JacinLarkwell]

I have some crosses I want to make, and I'm curious if anyone can help. I'd like to know which of these mutations I would get in the first generation

Naked Neck x Pheonix
(Mutations: Naked Neck and long tail)

Naked Neck x Arucana
(Mutations: Naked Neck, Cheek muffs, rumpless)

Also polydactylism and fibromelanisn. Will these be peasant in most F1 offspring when crossed with a parent who doesn't have them? I headed somewhere they're dominant

Na, naked neck, incompletely dominant
Gt, long tail, dominant
mt, non-molting of tail feathers, recessive
Mb, muff/beard, dominant (not in Araucanas in the USA)
Et, ear tuft, dominant, lethal in homozygous state (found in US Araucanas)
Rp, rumpless, dominant (I think this is the one US Araucanas have. There is also a recessive rumpless gene listed on that page.)
Po, polydactyl, dominant
Fm, fibromelanosis, dominant
Id, Inhibitor of dermal melanin, dominant, prevents expression of Fm

Naked Neck x Pheonix
(Mutations: Naked Neck and long tail)

I have done quite a few phoenix crosses. Long tail traits are incompletely dominant-offspring have a tail that will be somewhere between the phoenix and the breed it's paired to. Below shows phoenix/silkie cross-50/50 and a third generation phoenix/Polish cross-75% phoenix/25% Polish.

Alrighty, thanks
