chicken breeding experts please help!!!!!!

[chickenman98]

I want to cross a black tailed white japanese roo and a golden sebright hen. what will the chicks look like? i'm hoping to (probably after several generations) come out with a golden laced japanese. Which comb is dominant:rose or single? What about the tail will it stay long? And the colors and shape how can i get it to look like a japanese but be golden laced and in the end how can i get it to breed pure?
Thanks,
Ryan

Interesting side remark:
The genes for rosecomb and creeper are closely linked, or rather non-rosecomb and creeper.
Therefor you can not breed single combed birds anymore from this cross's shortlegged offspring (rosecombed japanese) alone.
These would be double-creeper = lethal.
