Naked Neck gene primer: just to be clear.
The naked neck gene is an incomplete dominant gene. Meaning a fully feathered bird cannot hide the gene to pass it on. One copy will show a partial naked neck and two copies will show a full naked neck.
2 copies: expressed as Na/Na. Called Homozygous. (we can call this "Hom")
Shows either a small bow tie or clean neck.

1 copy: expressed as Na/na. Called Heterozygous. (we can call this "Het")
Shows a bigger "bib".

0 copies: expressed as na/na. This is a normal fully feathered bird.

Breeding them together:
na/na (0) + Na/na (1) = 50% (0), 50% (1)
Na/na (1) + Na/na (1) = 50% (1), 25% (2), 25% (0)
Na/na (1) + Na/Na (2) = 50% (1), 50% (2)
Na/Na (2) + Na/Na (2) = 100% (2)
Na/Na (2) + na/na (0) = 100% (1)
and if visuals help better, the Na genetics can be overlaid right on top of a Black/Blue/Splash breeding chart as the gene works the same way.
Just sub Na/Na for splash, Na/na for blue, and na/na for black.

Thank you. I need the visual so the chart is helpful for me.
