heredity in chickens

[NeilsHamburgs]

Has there ever been a study done or does anyone know the inheritance % for certain traits?

Wow. That's actually a really good question. My best answer would be this.

Dominant: Single comb, frizzledness, occasionally collering of eggs ( mainly easter eggers).

Rescessive: wry tail,other combs than single.

Other than this, I would say just to be careful about frizzledness- two domanant genes for one chick can cause it to be crippled or die before hatching. Other things can cause the "deadly gene", but mainly this trait.

I don't beleive there have been any thorough studies of exact precentage, but you can get pretty close to what you want in your chicks by looking at the parents' dominant and recessive genes and traits.

Ok. So I FINALLY found the book that has a small list of dominant and recessice traits in it. (I was failing at naming the things on the list before and I'm sorry if you started using it allready)

So Dominant traits include: 5 toes
feathered legs
crests
side sprigs
and as I said before, frizzledness

Recessive traits include: 4 toes
stubs
single combs
wry tail
and silkiness

There is also another book it reccomends for breeding: Genetics of the Fowl by F.B. Hutt

"Deadly Genes" are when a chick gets the same lethal gene from both parents. It can cripple or kill your chick so... in general-- BAD. Though very rare, they can come from short-legged Japanese bantams, Araucana, dark Cornish, New Hampshire, and white Wyandotte.

Hope this helps.

Lots of studies have been carried out on the genetics of chickens. It is a complicated subject. What trait are you seeking information?

The short legs are caused by the creeper gene, and it is indeed lethal; not common in other breeds, but in breeds where extremely short legs are required by the standard, it is present in all birds that meet the standard. Ditto for the tuft gene in araucanas.

Leg color
Face color
Lobe color
Also trying to find out what causes wrinkles and dents to show up in wattles.

 

[tadkerson]

leg color is polygenic and is dependent upon skin color, the E lcous allele and a sex linked gene called dermal melanin.

face color has been researched but no conclusions have been published, Birds with black faces (and black skin)have white skin, sex linked dermal melanin and a gene called fibromelanosis.

black faces are also associated with birds that are birchen or extended black

ear lobe color is fickel and polygenic.

Its all complicated.

Dominant: Single comb

No...

No...

yeah, i corrected it in the post after i wrote that one..

.but i guess noone was payin attention...

You can not be too careful with these matters...
