Black silkies

[miss silky]

Anyone know what a cross between a spangled hamburg and a porcelein D'Uccle is? My silkie hatched them and also there's a black silkie and D'Uccle mix, cute!

Quote: no; not sure how you got that from what I wrote?

Recessive white (any recessive gene) requires two copies for it to DO anything. What this specific recessive gene does is prevent all pigment from being created.

A dominant gene requires only one copy be present to work. In the case of dominant white, it prevents black pigment from being transported from the melanocytes (where it is created) to the feather follicles. The transportation method is different for red/gold pigment, and it is unaffected by dominant white. Dominant white is used to build varieties that are red/gold and white such as red pyle or golden neck. To create a solid white bird with dominant white, you need additional genes that reduce red pigment. And two copies of dom. white is more effective than one.

I think I figured out your confusion: the definition of dominance. Genes are not dominant over other genes, and one colour is not dominant over another. A gene is dominant only with different alternatives (alleles) of the same gene. Blue (Bl) is dominant over not-blue (bl+), the recessive allele for this gene. Dominant white (I) is dominant over not-dominant-white (i+); for this explanation let's ignore the other dom. white alleles). Recessive white (c) is recessive to not-recessive-white (C). Every chicken has some allele of each of these genes (plus all the others); they all work together to produce the phenotype for that bird.

. Color question!! I got my black Silkie roo from a friend and have noticed he has some silver/grey underneath that shows up when he is has gotten wet. Is he a black or something else? It mostly shows up on his chest and feet. I love him and don't care what color he is just curious thanks in advance!

Unless you do some test breedings to a splash, you won't know... could be either dark blue or black. Some blacks have lighter down and not enough melanizers present. Some blues are way too dark... Can't tell from simply a picture.
