Turkey Genetics Feedback

IMHO, You seem to know everything about turkeys. You should probably start you're own site about turkeys soon. As I am sure it will be much work, you will be missed on this forum.

Thank you Laggerdogger for the info you provide. I am just a dumb old country boy but I find it very informative and I for one will not hold you responsible if the formulas are not perfect. I like mutts anyway

Thank you Laggerdogger and MissTurkey4 for the great info! In my experiments with creating my own golden Narragansetts, can you tell me if the below will work?

First cross of Narragansett tom to Red Palm hen = 1st gen
Second cross of 1st gen hen back to the Narragansett tom = 2nd gen
Third cross of 2nd gen hen back to the Narragansett tom should give me offspring that will breed 50/50 Narragansett and Golden Narragansett. Is that true or am I over-simplifying?

You've been busy--several more posts; your explaining very well; if I can understand it at 1 am you must be doing something right! Great resource to refer back to and reread and reread and reread! Thanks!

I think you've made it harder and oversimplified.

First let's see what you suggest.

Narragansett Tom X Red Palm is

b+b+CCngngRR X b1b1cgcgng--rr

so offspring are b+b1CcgngngRr toms and b+b1Ccgng--Rr hens. All of these will look like golden narragansetts.

Then you propose crossing these hens back to Narragansett toms.


Possible offspring hens include
1 b+b+CCng--RR
2 b+b+Ccgng--RR
3 b+b+CCng--Rr
4 b+b+Ccgng--Rr
5 b+b1CCng--RR
6 b+b1Ccgng--RR
7 b+b1CCng--Rr
8 b+b1Ccgng--Rr

Hens 1, 2, 5, and 6 have no red genes. They will look pretty much like normal Narragansetts (#1 is a normal Narragansett), but 2, 5, and 6 will carry other recessive genes.

Hen 3 is a golden narragansett, while 4, 7, and 8 will look GN, but carry extra genes. If you cross a narragansett tom with any of these 4 hens, half of the offspring (both toms and hens) will look like narragansetts, and half will look like golden narragansetts. But these offspring will probably be carrying various combinations of black-wing and palm (gray) genes.
If you keep breeding these birds, you will occasionally (or perhaps often) throw things that don't look like narragansetts, such as royal palm, red palm , calico, and things that look like palms with barred wings.

A simpler way would be to cross a bourbon red hen with a narragansett tom. This will give you golden narragansett hens, b+b+ng--Rr, which when crossed with Narragansett toms produce 50/50 narris/golden narris for both toms and hens, with no extra genes hidden in the background. And it won't take so long

I see another reason to keep searching for good Narrigansetts! I settled for Red bourbons to start with.

THis was my original idea: Narrigansett toms over BBB hens to produce F1's for market; hoping for a meatier carcass and still retain a traditional looking bird.

But because I have the Bourbon Red and BBW this year, I was considering keeping a BBW hen and cross it with the BR tom. Q: half will be white colored and half BR color??

I don't know if BBW are black based or bronze based. If they are bronze based, all the first generation will look red bronze, but will have a recessive white gene b+b+CcRr. If they are black based, they should look rusty black, but they will all have recessive bronze-based and white genes, Bb+CcRr.

Thanks Lagerdogger. It's not the result I was hoping for I wanted white feathering for a clean-looking carcass. Well, I certainly won't confuse the offspring with the parents and can keep track of the generations! TY

Hello,
I hate to step on anyones toes but just wanted to make some corrections here,all the toms from this type a cross would be carriers of a single ng which they would all receive from the narri hen as that is all she can give at that locus to her male offspring.

You also listed the female offspring as NgNg at that locus, it should actually be Ng-

I always put a - as the second symbol for hens in these sex linked genes.

Back in the 1930's Marsden and Martin listed the 1 non-functioning sex chromosome of hens "if it exists" as W, but today we list it as simply - to indicate non-functional.

Wow! I can't believe I made that mistake. That was my whole point in writing it. I am glad you confirmed everything I have been trying to say. I have had some problems with my computer erasing things so I some times write things twice without noticing. I am sure I did not proof read or I would have noticed. But most likely it because I am so sleep deprived. I had a baby two days before I wrote that. I am still so tired. My baby is in the hospital in very serious condition.


Thank You!
