Silver Inheritance?

[Labelles Velders]

Just as I predicted, didn't I?




Autosomal red has little effect on columbian restricted hens.





Due to Melanotic being in Homozygous state(from both parents) the leakage will only be restricted to the breast and underside due to heterozygous columbian.

So what do you know about these hens (EE hen and Mixed F1), in terms of loci and such? Like Co, Ml, etc? I only know the very basics and don’t know what to gather from their appearance.

Also, what affect would a parent having Autosomal Red have on these F1 offspring?

It could vary from no red at all to light red patches on the back and wings.

Thank you!

The mother seems to express the pattern gene on e^b partridge.
However, I am not certain.

Regardless, her pullet offspring would be an incomplete columbian pattern.
That means it would include partridge e^b/e^b, columbian Co/co+, pattern gene Pg/pg+, silver S/-, and charcoal Cha/cha+

Thanks for taking a closer loo a the EE hen, I also see the pattern gene on her.

More info on recessive charcoal(cha/cha): It was discovered by Dr. Crawford in 1986 from a line of Melanized wheaten Game, at first he believed it was Melanotic but further research by Dr. William Clive Carefoot confirmed it was a different gene(recessive charcoal is linked to the pea comb very closely, while Melanotic segregates independently). Cha+ is the dominant wildtype form and cha is the recessive autosomal mutation(that is also how is found on my friend Mr. Henks chicken calculator)

Excerpt from the outstanding work by the late Dr. William Clive Carefoot: Test for linkage between the eumelanin dilution blue (Bl), the extended black (E) allele at the E-locus and the linked pea comb (P) and eumelanin extension (Ml) genes in the domestic fowl. Carefoot, W. C. 1990

"Linkage of 0.3% had been previously reported (Crawford, 1986) between P and a "melanotic" gene isolated from a segregating gene pool. Evidence is presented to demonstrate that two different "melanotic" genes were being considered, thus explaining the apparently contradictory reports. Charcoal (cha) is suggested for the recessive gene linked with P by 0.3%"
