If the peach pied white eye male is carrying one copy of white eye gene (where in you see only a few- may be 20 white eyed TRAIN feathers) = 1) all the chicks will be peach. 2) 50 % will be split to white, 3) 50% will be split to pied. and 50% will have some (again may be 20 or so) white eyed TRAIN feathers. The white eyed gene may combine with white or pied but not both. On the other hand if the male is carrying 2 copies of white eye gene It is called a peach silverpied, all the chicks will get one copy of white eye gene. By the by, white eye gene, they say is self expressive independently all by itself, Can not be masked by any pattern gene or colored gene except two white ( TT) genes.
