Naked Neck/Turken Thread

[Georgia Boy 1970]

Breeding back to Fibro-melanistic hens should give me some dark fibro chicks.

I am trying to find the naked neck breeding chart that was posted on this thread.Thanks

Do you mean this info?
Key:
NN = homozygous for naked neck gene; either clean-necked or very small bowtie (a few feathers)
Nn = heterozygous for naked neck gene; bigger "muff" in the front of the neck, naked back of neck
nn = fully feathered (either Naked Neck derived or any other breed)

Expected outcomes of crosses:

NN x NN = 100% NN
NN x Nn = 50% NN, 50% Nn
NN x nn = 100% Nn
Nn x Nn = 25% NN, 50% Nn, 25% nn
Nn x nn = 50% Nn, 50% nn

Yes,thank you.

Yes,thank you.

You can reproduce it yourself if you use the Punnet square method, which is a way to see the outcome of any cross for a single allele/locus where the genes are not sex-linked and inheritance is simple/straightforward (which it is in this case). Here's one I just made up to show you how you could tell that a cross of Nn and Nn gives you 25% NN, 50% Nn, and 25% nn. The parents are on top and side, then you combine the alleles for each possibility of offspring....


Hope that helps - you'll never have to look it up again!

I am not familiar with genetics, so I am sorry if I ask stupid questions.

are all naked necks either NN or Nn? does it mean that they will always hatch at least 50% naked necks (either NN or Nn)?

I never understood Punneg Squares myself. I don't remember even studying them in school. I understand this way much better.

Expected outcomes of crosses:

NN x NN = 100% NN
NN x Nn = 50% NN, 50% Nn
NN x nn = 100% Nn
Nn x Nn = 25% NN, 50% Nn, 25% nn
Nn x nn = 50% Nn, 50% nn

N is the gene that confers "nakedness". n is the version that is fully feathered. Every bird has two genes. NN and Nn will have nakedness of various degrees, as noted below. But if you cross two Nn, you'll get (roughly) 25% nn (fully feathered).

NN = homozygous for naked neck gene; either clean-necked or very small bowtie (a few feathers)
Nn = heterozygous for naked neck gene; bigger "muff" in the front of the neck, naked back of neck
nn = fully feathered (either Naked Neck derived or any other breed)

NN x Nn = 50% NN, 50% Nn
NN x nn = 100% Nn
Nn x Nn = 25% NN, 50% Nn, 25% nn
Nn x nn = 50% Nn, 50% nn

Yes, I posted that, too, in a previous post - I was just thinking that it might be useful to see the Punnet square as well for some people - you can calculate the percentages without having to memorize it that way.

Thank you, very helpful

Weights, measures and photos are complete for the week and I'm pleased with several of my NN chicks so far. Since I've got nearly 2 dozen I'm only going to post photos of some of my favorites:

Here's the latest image of Ozzy, who really didn't enjoy being photographed. His feathering looks kinda awful, but he's got the highest growth rate in this group since hatching at over 866% since day 1. The big surprise for me are the reddish feathering coming in on his neck.

Princess, my favorite of the chipmunk pullets.

Another of the chipmunks, and another that's keeping me guessing about gender.


Ruby: I originally thought this was a pullet, but now I'm not too sure.

Pepper, my Austrolorp/NN mix...and probably the sweetest bird in the whole flock. And big!


No name yet, but a handsome little cockerel.


And now a couple of Mama Lily's chicks. Since she decided to move on I added them to my "incubator" chick flock, but they're 5 weeks old, not 4:

Zazzle - a nice robust cockerel weighing in at 14.82 ounces.

Jagger, the second cockerel in this group.



I'm a little disappointed in overall growth rates compared to their parents, but there are a few relatively promising birds in this flock. And a lot of pretty ones! (In my humble opinion.)
