Put a duckwing (e+, wild type, as in brown leghorn (light)) male onto a barred female. take the barred male from this cross & put onto duckwing females. All things being equal about half of the offspring will be duckwing & about half of the offspring will be barred giving odds of about 1 in 4 being crele. In order to make bred true breed the crele offspring together, females will be fine but select for males wih two barring genes.
can some one post the crosses in breeding it takes to create the crele?
As Krys said or the other way is to:
Catlin (1991) describes how he made his own strain of Creles by crossing two Crele males with two unrelated Black Breasted Red females. From the mating all the sons were dark
(intermediate) Creles and all the daughters pure Creles. By crossing first generation males and females he extracted some pure Crele males to go with the pure Crele females already obtained.
