Porcelain always has the gold gene which is why it's yellowish. It doesn't carry it it is homozygous. But Porcelain also is homozygous for the lavender gene which dilutes gold to cream.

If it carries just one then that would be a yes. That may not be how it should be tho. That would mean that hens should be S and cocks should be S/s+. If hens where s+ and cocks where S/s+ you would still end up with some that are pure silver on the hen side only I believe.

Thank you both

The difference between the two varieties is the lavender gene (dilutes black to light gray and gold to a light yellow/cream). Because the lavender gene is recessive, you only see a porcelain bird if it has two lavender genes. When you breed two porcelains to each other, each parent has two lavender genes, each chick inherits two lavender genes, and each chick is also porcelain in color.

If you breed Porcelain to a normal Mille Fleur (no lavender gene), all chicks should look Mille Fleur but carry the lavender gene. Breeding those chicks to each other or back to Porcelain would give some Porcelain (two lavender genes) and some Mille Fleur (one or no lavender genes.)

Ok that make sense. Thank you

@nicalandia
It's been a while since you've been here but I believe you'll come back so it's worth a shot.
I tried contacting Dr. Okimoto about the discrepancy, but he hasn't responded to my emails (I tried different email addresses for him.)
Basically everyone who has been in contact with Dr. Okimoto on The Coop forum lists the Smoky allele as dominant to Dominant White.
But the only published research on the gene (which he co-authored) lists it as recessive to dominant white: https://pmc.ncbi.nlm.nih.gov/articles/PMC1448810/
Did he discover it was dominant after it was published and only told those on the Coop forum? Why does everyone who credits him with their info on Smoky say Smoky is dominant to Dominant White when his research says otherwise?
I believe there must have been some discussions on The Coop about this. But unfortunately the forum went down before my time so all of those discussions cannot be traced.

Random genetics question:

• Earlier this year I placed seven big green eggs beneath a hen
• She hatched seven 1/4th Ameraucana chicks
• This one has white legs somehow despite all my green egg layers having slate legs
• Zero white legged roosters here

Is it possible for a yellow legged roo and a slate half Ameraucana mom to have a white legged child somehow?

This is the chick in question. Small beard and muffs are visible. I have zero white legged Ameraucana mutts and zero white legged roos. Somehow he has white legs

Is it possible for a yellow legged roo and a slate half Ameraucana mom to have a white legged child somehow?
Yes
That is the expected outcome.
In layman's terms:
Yellow legs means the bird has the yellow skin gene and non-slate gene.
Slate legs means the bird has the white skin gene and the slate gene.
White means the bird has the white skin gene and the non-slate gene.
In non layman's terms:
Yellow leg genotype is: yellow skin gene and dermal melanin inhibitor. w/wId/Id
Slate leg genotype is: white skin gene and dermal melanin gene. W+/W+id+/id+
White leg genotype is: white skin gene and dermal melanin inhibitor. W+/W+Id/Id
Your rooster has each of the skin color alleles: W+/wId/id+
Since white skin is dominant to yellow skin and dermal melanin inhibitor (nonslate) is dominant to dermal melanin (slate), he will have white skin.

Does anyone know what makes a fawn sport? I'm starting from scratch and can't really find any chickens near me so I'm stuck with the hatcheries. I have silver/ golden duckwings and white pheonixs coming in April. My goal for now is to make a fawn duckwing. I asked around on fb groups and was told fawn sport x silver duckwing will give me fawn duckwings but cant get an answer on how to make a sport. Thanks.

Fawn works like blue. So you have normal black, fawn and khaki. Khaki is the sport. If blue is Bl/bl and splash is Bl/Bl then fawn is F/f and khaki is F/F. Those are not the right gene markers but are being used as a short cut here. Splash is the sport of blue and Khaki is the sport of Fawn.

So what is the OP calling a fawn sport?
From their post it sounds like a khaki silver duckwing, right?

That's what I'm assuming. Its all I could get from what was said. I know OEGB call the splashes from the blue and fawn colors Sports.

You wont get fawn from most hatcheries. Look on eBay for hatching eggs for OEGB. I've gotten fawn crele from there. Fawn crele is just fawn silver duckwing with barring.
