Hello,
I have a question about the genetics of feather growth genes. I know that when you breed a Rapid feather growth breed male (like a Leghorn) to a slow feather growth female (Like a Rhode Island Red), the F1 offspring is wing feather sex-able, but what do the future generations produce? If those F1 Pullets are bred back to the Leghorn, what percentage come out rapid feather growth... 50%? And what does the second (F2) generation throw?
Thank you!
 
The Leghorn male is fast feathering/fast feathering and the F1 females are fast feathering (they only carry one gene) so when bred back together 100% offspring will be fast feathering.
F1 cockerels are fast feathering/slow feathering so if they're bred to the F1 pullets, back to RIR or Leghorn hens the pullets will be 50% and 50%.
Cockerels from the F1s or Leghorns will be 50% fast feathering and 50% fast feathering/slow feathering.
With the RIR 50% slow feathering and 50% fast feathering/slow feathering.
 
Ok, thank you, The Moonshiner.

Perris, I followed this link and found this:

It says the Rapid Feathering is Recessive, that gene will be present in the F1 generation, is it Sex liked recessive? Also, the ‘Very slow feathering gene’ at the bottom, if I use one of in replacement of the RIR, will the offspring be wing feather sex able?
Thank you!

sorry I can't help you with that, but @The Moonshiner might be able to.
 
All good, Perris.
Do you know, The Moonshiner? The reason I’m asking, is I’d like to start working on some feathering projects, to produce wing feather sex-able birds that are not generally a color feather sex able color. I believe Cackle hatchery and some other large scale breeders have achieved these goals, I would like to do the same in more unique breeds.
 
No I don't, but they seem to know a lot about this and have already replied to this thread, so it seemed natural to tag them and ask :)
