what do you get when you cross chocolate(not dun based) and splash?

Hi guys,

This is where I read my info on chocolate. The link to the chocolate gene is at the bottom of the page ...... http://keiths-orps.co.uk/categories/bantam/chocolate.html ......

You have just contradicted yourself though, you say chocolate is not the same and don't have a recessive gene where kidw carry and not show it , but DOES need two copies ....



The chocolate gene is one of the few known Sex-Linked recessive genes in poultry. It may seem difficult to grasp at first but if a female carries Chocolate, then she will be visually Chocolate. However, males require two copies of the gene for them to appear as Chocolate. Black males can carry a copy of Chocolate without it being at all identifiable. The only way to tell is to test mate. However if the mother of the Black male in question was Chocolate herself, it is certainty that all her sons will carry a single dose of the Chocolate Gene. I don't know how it will work with a splash boy but could be fun finding out !

Not sure if I used proper terminology but I know choc roo(which has to have 2copies of choc to be visually choc) x black hens results in choc pullets and visual black(carrying a copy of chocolate) cockerals. That wasn't what I was looking for an answer to if I added splash. I got my answer...a very intuitive member knew what I was up to and pm'd me my answer and it removes the splash factor altogether.

correct Mauve is a cross of Chocolate and Blue(Bl/bl) so a choc/choc and Bl/bl, kinds of look like Platinum Blue, wich is het dun(wich looks like chocolate anyways) and Blue(Bl/bl)

Black Roo and chocolate should make just black... if your male has a chocolate gene it will have 50% black and 50% black with the chocolate gene.

(It's what I have written in my book anyway lol )

Chocolate (choc) is sex-linked recessive. Chocolate is like gold and silver, the male can have two doses and the female only one, because its on the sex chromosome. So a chocolate cock has two doses of the chocolate gene to express it (its recessive so one dose won’t express!) and the female needs only one dose to be chocolate to express it.
The counterpart of sex-linked is called ‘autosomal’, that means on both sexes the same expression of a gene.

Dun colour is autosomal, it looks/acts the same on the hen and the cock. Dun colour is a bit of a weird gene because its located on the site where dominant white is located too. Dun colour is an allele of dominant white.
Best comparison of Dun is with blue. One dose makes the dark brown dun, hobby name "chocolate" in some breeds like Old English Game Bantams and Polish. Two doses make dun splash, hobby name khaki. Dun color breeds as follows:

Most breeds called "chocolate" in the U.S. are relay Dun.

careful. Autosomal does not exactly mean that a gene expresses the same on both genders.

from kippenjungle http://kippenjungle.nl/basisEN.htm
With normal (=autosomal) inheritance both genders are equally mocked up by distribution and expression of genetic traits. No statistical differences can be seen between the genders of the offspring.

Some genes, shouldn't matter if sexlinked or not, express differently on each gender. For instance Columbian has more power on male phenotype. Still it is autosomal.

Clarification. Meant is thát a gene expresses (or not) among the sexes, not to which degree it does express on each sex.​
