Most think its a dilution still so I'm sticking with that until proved other wise. It very well could be tho. And it still shows out that most black dilutes work like blue does. If pumpkin is not a real dilute then that would make it different. Could it be both? A dilution and a pheomelanin extension?

I want them to find all these genes for chicken colors so I can stop guessing. Then we can have colors that match gene names and I wont be confused by the jigsaw of all these color names as well.

Sexlinked chocolate and I would argue dominant white (being co-dominant as opposed to incomplete dominant) do not work like blue.
Pumpkin isn't a black (eumelanin) dilution because it causes the bird to produce pheomelanin rather than changing the shape of eumelanin or causing eumelanic areas to be less densely pigmented by interfering with eumelanin production.
Pheomelanin is by definition not a black dilution. Pumpkin birds still do have black on them so the bird isn't simply producing red instead of black either. However, I would argue that genes that do produce red instead of black aren't black dilutions either because they are increasing the amount of pheomelanin present.

Oh I did forget about white, lol. And I do stand corrected. Brain miss fire and stuck on a completely different track.

That's a good explanation and makes more seance that what a lot of others say about it.

It's been very interesting seeing you two discuss the generic make up of the pumpkins.
I've often wondered the same things with how their color generic work.

@Amer , where and how did you get the knowledge you have about genetics?
I would love to learn more to benefit my own breeding.

Dude, and everyone kept saying it wasn't a good old English turn out.....:th

Hopefully I'll have a couple cages with my birds in the show come fall. 😎

Well, they are the most popular breed...

Well I started by learning a lot of the structure genes and leg color genetics here... because it's simpler
https://www.kippenjungle.nl/chickengenetics/mutations1.html
Then I moved on to what is now my favorite, color genetics. I learned from the Kippenjungle calculator, along with nicalandia here on BYC. If you click on my signature you can see read the sum of what I've learned...
What I've posted, anyway.
