white

The problem I have found with using wild type birds is that if the White bird is "hiding" Gold then you will never know. Where if you first cross to Black then the chances are good that if the White bird is hiding Gold then it will show up in the hackles of the offspring.

Chris

that just doesn't make genetic sense at all.. you can do the same with wildtype

let me explain this...

first scenario the bird is Dominant white(all white) Crossed to Gold Wildtype..

chances are his genetic make up is E/E I/I s+/s+ but lets add Splash to the mix Bl/Bl

when crossed to gold(BBR) Wildtype the cross will be E/e+ I/i+(leaky whites) Bl/bl+(blue) this will produce leaky whites(leaking black and ground color) they will be all white with some blue color leaking(beause of Blue Bl/bl+) but thats only because we added blue to the genetic make up but if there is no blue, then the leaking parts will be black,

chicks will look like this


if the rooster is Hiding Barring then the leaky black feathers will turn out barred, Now Chris09 said he was expecting some gold feathers to leak thrue but when crossed to black, well the same thing will occurs, if the white bird is hiding gold some gold feathers will pop out on the hens and roosters(if the wildtype is a gold wildtype)

*********************************************************************************************************************************

second scenario the bird is Dominant white(all white) Crossed to Black


chances are his genetic make up is E/E I/I s+/s+ but lets add Splash to the mix Bl/Bl

when crossed to Black(E/E gold s+/s+) the chicks will have a genotype of E/E I/i+(leaky whites) Bl/bl+(blue) this will produce leaky whites(leaking black and ground color) they will be all white with some blue color leaking(beause of Blue Bl/bl+) but thats only because we added blue to the genetic make up but if there is no blue, then the leaking parts will be black,

chicks will look like this


if the rooster is Hiding Barring then the leaky black feathers will turn out barred, Now Chris09 said he was expecting some gold feathers to leak thrue but when crossed to black, this much is true


********************************************************************************************************************************************************

Scenario 3

bird is Recessive white(all white) Crossed to Gold Wildtype

since Wiltype gold is recessive to just about anyother dominant gene out there except recessive genes like recessive white and other recessive genes like mottling, this will show any and all dominant genes present, not to test for recessive genes you will have to do a F1xF1 cross, this will yield more recessive white birds and any other recessive gene present on the white birds..


*************************************************************************************************************************************************************************************************************

Scenario 4

Bird is Recessive white(all white) and Crossed to Black...

Since Extended Black(E/E all black) is dominant to just about anyother gene, the birds will come out looking all black with gold/silver color leaking thrue.. leaving behind anyother genes hiding under the black(except for blue, barring, dun)...


so as you can see its Always better to use a Wildtype bird, just think about it, why do all of the genetic research done on labs us the Red Jungle Fowl? becasue its the "Wildest" of the Wiltype birds, but sinse you cant get your hands on a RJF, a gold wiltype is your best option.. many genes were extracted by using the Wiltype Red Jungle Fowl one of them is of interest of me, its called the Dilute gene

If you cross Dominant White with Wild (BB Red) the F1 offspring should be White with Gold leakage in hackles much like a poorly marked Pyle when feathered.

Chris

not Nearly as Pyle but with a lot of gold leakage, thats why I was confused when you said that you could not tell if a bird was gold when you cross it to wildtype, I´m glad you came around...

i will try to do both black and bb red if i can find some. remember this is a white d'uccle rooster this wouldn't take place till next year so plenty of time to learn about it.

what would happen if i threw him over some breed with a pattern such as my porcelain?

porcelain is mottled lavender and Columbian restricted.. on your first cross, you wont be able to see lavender or mottled at all, because they are recessive, now the columbian gene is dominant but it has no effect on extended black so I wonder if you will see any effect at all, maybe some ground color leakage

 

[hdowden]

would be interesting to find out.
