Chocolate Gene

[TurtleFeathers]

Here's my WC chocolate (or dun?) Polish hen (she's alittle scruffy here, but you can see her color):

I'd like to see a pic of a chocolate serama, if anyone has one?

I am not to up on genetics. All i know is they are chocolate and they produce chocolate and kahki. Why would that be called dun?

Because in this instance Chocolate & Khaki are hobby names, the genetic name for I^D is Dun.

These are sexlinked chocolate japanese recently made from serama:

I think the choc gene is equivalent to the duck's d-gene.
Most birds have a sexlinked brown dilution gene.
Ducks also have buff dilution, sexlinked, and this might have a brown dilution effect also.
Note that khaki in ducks is much darker than chicken khaki.

Henk69 those chocolate japanese are beautiful.
I wonder if I could do that.If you don't mine sharing how you did this, please share!

How did you get a chocolate serama?

How do you tell if that particular serama is sex linked?

Did you start with a chocolate serama cock and mate them to black japanese bantam hens?

First of all. These were created by Sigrid van Dort the writer of the populair new chicken colour genetics book (see chickencolours.com).
She got her seramas from Jerry S. in the US.
She crossed melanized chocolate silver duckwing serama cock with self black japanese bantams.

She then noted that only pullets became chocolate.
Sexlink proof:
I got a few split brothers of those pullets, these were melanized black het silver duckwings. These were crossed to black frizzle japanese of my own.
This cross produced chocolate pullets (there is your proof) but all these where wheaten based columbians, very little chocolate parts. I sold them.

Problem about Jerry's serama. They may be chocolate or they may be dun (or both). He doesn't care for genetics.

Most birds have a sexlinked brown dilution gene.

It's a long time since I've dabbled with duck genetics. Is it that d dilutes only black whatever other genes are present?​

I would think just because of the difference in the richness of color between chocolate and dun from what I have seen, that they are dun. Pure speculation though....​

I think so. The documentation is pretty vague. Especially the photographs.

I made a few videos of dun and chocolate animals alongside each other.
Shall I upload them?
