Skin (Feet, Legs, and Beaks too) Color Genetics

[ColtHandorf]

So I'm working with Silver-laced Orpingtons and am really enjoying them. I just picked up some new breeders that have excellent type and the correct leg and beak color (white) but their lacing is soft and not very crisp. My original pair of SLO have gorgeous lacing and great size but have distinctly yellow legs. Like Wyandotte yellow. They threw one Golden-laced chick out of the last clutch that has slate leaning towards willow legs possibly? They certainly aren't yellow like the SLO siblings. Anyway, how hard is it going to be to get that great lacing and the right leg color on the same bird? Is yellow dominant over white? If I breed my yellow-legged originals to the white-legged new bloodlines, will I get all yellow split to white? I'm clueless when it comes to this stuff...

White is dominate to yellow. You need two copies to show yellow.
Not good news huh?
All your yellow leg birds will pass a copy so you can end up with the yellow hiding for some time in white legged offspring your producing.
Eventually you'll have to test breed to make sure you have no carriers.

Thank you! That's exactly what I needed to know.

white skin= W+ (Capital letter because it's dominant and the plus sign to identify it as wildtype)
recessive yellow skin= w (lower case, recessive)
Sex linked Dermal Inhibitor= Id (Capital letter because it's dominant)
sex linked dermal enhancer= id+ (lower case, recessive wildtype)

W+/W+, Id/Id = White skin and White shanks
W+/w, Id/d+ = White skin and White shanks
W+/W+, id+/id+ = White skin and Slate shanks
W+/w, id+/id+ = White skin and Slate shanks

W+/W+, Id/Id, Fm/FM = White skin and White shanks
W+/w, Id/d+, Fm/Fm = White skin and White shanks
W+/W+, id+/id+, Fm/Fm = Dark Blue/Black skin and Dark Blue/Black shanks
W+/w, id+/id+, Fm/Fm= Dark Blue/Black skin and Dark Blue/Black shanks

w/w, Id/Id, Fm/Fm = yellow skin and yellow shanks
w/w, Id/id+, Fm/Fm = yellow skin and yellow shanks
w/w, id+/id+, Fm/Fm = Dark Green/Black skin and Dark Green/Black shanks
