I have noted that the blue gene has been described as a dominant gene on this thread. The blue gene is not dominant but incompletely dominant. If the blue gene was dominant, then one blue allele would cause a genetically black chicken to be a splash phenotype. The blue allele by itself can not...
To get a light buff (not assisted with dominant white) as in a buff orpington, the E locus would have to be changed in the polish from Birchen to wheaten or wild type. The gold laced polish is a darker buff color because of the black that is in the feathers. The dominant white gene removes the...
For practicality, I will say no, the gold parent does not have the correct genes to produce buff offspring when crossed with a bird that is a hybrid. The hybrid itself is problematic.
Your F1 may carry blue, is most likely extended black/birchen at the E locus, may or may not carry two...
Buff laced polish are as you stated not silver. If they were silver, the bird would be almost completely white. All the buff on the bird would be replaced with white if it carried silver.
For grins- lets make a buff and white laced polish chicken. We will start with the base coloration and...
The male could carry gold ( makes red) or silver- you do not know because he is black under the white. If he had red showing through the white he would have red showing through the black in his plumage.
splash birds are actually black birds so when you cross two blacks you should get blacks...
All the other posts did a good job of explaining things- but I want to expand on the other posts.
You are confusing dominant white with sex-linked silver. They are two completely different genes and are inherited in a different manner.
Dominant white is a gene that inhibits black in every...
I would suggest that you use birds that are sex-linked silver to cross with the whites. Most recessive white birds do not have a problem with the gold allele expressing color in the plumage, I have read some research and the researchers did discover a recessive white allele that was leaky. If it...
the white in the hackles is due to sex-linked silver. Your bird appears to be extended black at the E locus and is missing the melanotic gene which would cover the white in your bird.
The male is a white-tailed red phenotype and the female is as black breasted red. If you cross the two you will get black tailed red and white tailed red offspring. The male offspring will not be completely restricted, but with red plumage similar to the male parent; some male offspring will...
That looks like a dominant white bird and it also has to be blue. Dominant white does not work on red pigments- so some red is being expressed in the feathers. Your male is dominant white. It is not unusual for the feathers of some white birds to show some yellow as the feathers wear.
Your...
yellow was the down color of the chicks not an adult plumage color. Forget the concept of a yellow chicken in this thread.
A completely white rooster (one copy of dominant white) x what is the variety of the hen= ?????????
A completely white rooster (one copy of dominant white x blue...
Everyone did a good job of explaining things. I would like to add some additional thoughts.
You have to understand there is a difference in birds that are partially white and completely white.
The following assumes the completely black male has not had any completely white birds in his...
The chicks look as if it has a down color characteristic of chickens that are brown at the E locus. Sometimes a birchen/wheaten heterozygote will look like the brown down. My prediction is that it will both be a basic black color with some red showing. I am going with birchen,wheaten...
Black ( blue) male parent x white female parent = F1 offspring
F1 male x white female parent = BC1F1 offspring
If you want more whites, back cross an F1 male offspring to the female white parent and some of the BC1F1 offspring will be white.
Also the pea comb ( in the brahma cross above)...
Any trait that is controlled by a set of genes can be inherited by the offspring. You are correct about back crossing. If you cross an ideal breeder with a less than ideal breeder, the offspring may or may not be ideal- then you back cross to the ideal breeder to obtain a better trait in the...
