Chocolate/Dun Silkies?

[onthespot]

Also, it was stated earlier that there were not great records kept, so no way of knowing which roos are from which hens. She would not know if the roo she uses on a chocolate hen would be a recessive carrier of sex-linked recessive chocolate, or if the hen herself produced a dun. Only better record keeping the second round would clear up the confusion. We will all know a lot more in the spring, if the OP is still feeling like posting here, which they might not, seeing what this thread has turned into already. Please post your results next spring, OP. Please? Thanks!

How is this?
If a True Chocolate hen only needs one copy of the gene to become Chocolate shouldn't the female out of a Black rooster / Chocolate hen be Chocolate?

Chris

Chocolate hens can only pass their gene to their sons - and because the rooster was black (not split to chocolate), the male offspring will be split. Female offspring can only inherit the gene from their father (and will only be visual) - even if their mother is a non-chocolate.

In addition to good records, she would need to get an unrelated solid black rooster from a long line of black x black breeding. That and she'd have to enclose them in a pen that can't be visited by any other roosters!

I, too, would be very interested to know the results of any test breeding! So please, Michelle, keep us updated, ok?

Whats the difference between dun & chocolate?


What needs to happen for dun to become chocolate?

They are different genes, with different inheritance patterns that both can produce similar looking birds.

 

[RioLindoAz]

I understood that the CHOC gene originated from the DUN gene. Is this correct?

If so, how is it possible to get some Chocolates from Duns? Or is there no connection whatsoever?

 

[TurtleFeathers]

Its my understanding that they are totally separate with no connection, and one was not derived from the other - but then again, I'm not a geneticist...

No, completely unrelated genes that have nothing in common with each other except that they can each create similar colouring.

Problem is, dun is often called chocolate, and it looks similar. Dun is an allele of dominant white, I^d, and chocolate is a sex-link recessive, choc. If you're buying one, be sure to ask for clarification. The seller may not even know the difference, so you can deduce the truth by seeing the parents, siblings, and offspring.
