The Pattern Gene on Wheaten
Pg (pattern gene) can also create patterns on the e^Wh (wheaten) base, and while these patterns aren't widespread, they are common in Cornish.
It is interesting to me that while it is the lightest e base wheaten produces some of the darkest patterns, while E^R creates patterns with the least amount of black. This is only possible due to the melanizing affect of charcoal (cha).
The Cornish version of double laced is known as "dark." Bantam dark Cornish are usually Wheaten based. Large fowl dark Cornish are Partridge based. The way you can tell what E-base your birds have is to look at the chick down. The dark genotype is e^Wh/e^WhMl/Mlcha/chaMl/MlMh/Mh. They may have some additional genes that make them darker.
The source for this photo was sus but I really struggled to find a dark Cornish bantam male so if you have a better one that you'd like me to feature, let me know!
Laced Cornish
Laced in Cornish has black or diluted tails. I have recently discovered their necks can and should be laced as well but those are the Patridge-based white-laced reds. Thanks to the Charcoal gene, the Wheaten-based bantams will have mostly solid-colored necks.
I haven't seen any black laced red Cornish, only blue laced red, or like in this picture, white laced red. The existance of blue laced red implies black laced red and splash laced red exist (and some splash laced red are probably exhibited as white laced red) but I digress.
All I have a picture of is the white laced red so I will stick to that. ("I" represents dominant white)
