BYC Genetic/Breed Calculator Huge Task Ahead!

Oops, forgot the picture of the Ameraucana egg in whole.

Forgot to mention that I'll also be adding the genetics controlling skin color to the spreadsheet.
I should be able to finish the comb genetics by the end of the day.

Wonderful. Want me to help by saying genetic makeup of these traits, or fact check the spreadsheet?

I have the comb genetics covered; I know exactly how those work. It would be extremely helpful if you could find the genetic makeup of leg color for me If you're willing.
If not, I can do it. It will just take me a while as I'm pretty busy until the weekend.
I will post the share link for the spreadsheet once I get it going, and feel free to fact check it.

I have to take my poor dog to the vet soon. She's got some sort of immune/skin disorder It keeps coming back and we're afraid that the vet is going to tell us it's terminal. It's definitely genetic. I we won't have to put her down for it in the long run. She's only 3 years old.

I'd LOVE to study leg color genetics. I can fact check later. Sorry about your dog though.

R. Okimoto :

Walnut and cushion comb are the same things. There are modifiers that make a rose comb smooth or bumpy. Wyandottes have the smooth short rose comb coming into fashion. While rose comb bantams still have the long pointed rose comb with bumps on it. Cushion comb probably has the smooth modifiers.

The buttercup comb is due to another dominant gene D. The buttercup comb is less dominant than the Lefleche type two horned duplex comb. The alleles are called Dv for the most dominant duplex comb and Dc for the cup type comb. Dv is found in Polish and is associated with cavernous nostrils (big nose holes in the beak). The Dc allele seems to cut the single comb down the middle and makes two combs. The buttercup allele is probably responsible for the stag horn duplex comb found in some Houdans. The crest modifies comb morphology by shortening the comb and pushing it more to the forhead.

The standard states that Silkies have walnut combs, but the original silkies had a trifid comb. The trifid comb was characterized by Punnett as being a rose comb variant. He did not see pea comb in his silkie crosses and he was the one that determined the genetics of walnut comb, so if Silkies had walnut Punnett was the guy that should have known this.

There is a recessive combless type called Breda. The original wild Red Junglefowl had combless females. These seem to be extinct in the wild and the wild populations seem to have domestic blood in them now. There is still a line of Red Junglefowl in the US that has the original type.

Can anybody confirm or deny these claims?
Considering that one specific line of Junglefowl left I am now more sure than ever that I don't want to add them to calculator.
I am not going to mess around with that recessive combless gene. It is highly unlikely it would ever come into play, anyway.

I think we should leave the Red Jungle Fowl out...far too much diversity in its genes

hope not.

White shanks is WW or Ww, with simple dominance over yellow ww.
Some say that skin color is only affected by pigmentation to the dermis, however, reddish pigment often comes in yellow legs, meaning it could be also effected by reddish feather color. (It can also be affected by testosterone, which explains why the pigmentation is often in the flock leader's legs)
Dermal melanin (id+) is a sex linked gene. Females carry two copies and males carry one. It is affected by five different alleles, (which I will try to figure out later.) Some plumage colors and patterns will be affected more than others. Like barred chicks. Dominique people (ok, cuckoo whatever) have fair success sexing chicks by the color of their legs. Girls have darker legs than cockerels. Typically.
Fibromelanosis, which causes black skin, organs whatnot in chickens can also cause dark pigment in shanks, which could possibly mean (I'm only guessing) that a fibromelanistic bird might actually have genetically white legs. I dunno. I got my info from here. https://scratchcradle.wordpress.com/2012/09/02/gms10-skin-and-shank-color/
White skin is WWIdId with variable E alleles, so dominant for white skin as well as no dermal melanin.
Slate is WWidid with variable E alleles, so that means that it has white shanks and dermal melanin.
If you got my drift you should already guess that yellow is
wwIdId with variable E alleles, absence of white shanks and dermal melanin
You may also guess that willow(green) is wwidid with variable E alleles, because if you add blue and yellow you get green.
Black with white soles is WWididE or Er I'm assuming these E genes make the pale soles on black feet.
Black with yellow soles is wwIdIdE or Er

Yup. And I have the book too.

I thought you said britiish?
